Description

Printing device and method for controlling the printing device

technical field

The present invention relates to a printing device that performs printing based on data in line units and a control method for the printing device.

Background technique

Conventionally, there is known a printing device that prints on a printing medium in line units based on data input (received) from an external device (control device, host device) (for example, refer to Patent Document 1). This printing apparatus includes: a controller unit that generates line-by-line print data based on data input from an external device; and an engine unit that prints an image on a recording medium with a recording head after receiving the print data from the controller unit.

Patent Document 1: Japanese Patent Application Laid-Open No. 7-205498

However, in the case of a printing device that performs printing in line units as described above, character codes and image data (image data) are sometimes included in data input from an external device, and line copies are performed based on these character codes and image data. printing. In this case, the print data for one line generated based on the data includes both font data and image data (at least a part of the image data) corresponding to the character codes and built in the printing device. In this case, when the character height (the number of dots in the height direction of the character) of the font data corresponding to the character code is different from the height of the image data (the number of dots in the height direction of the image data), in order to print all the contents In one line, the feeding amount of the printing medium for one line is determined and executed so as to match the one with the higher height (the one with the larger number of dots). Thus, for example, when the character height is higher than the image data height (in the case of "character height > image data height"), the image (image) based on the image data is not printed in the portion where the image data is printed. , and only the amount of "character height - image data height" is fed. When printing multiple lines including font data and image data in one line, if the height of the characters and the height of the image data are different, a gap will appear at the boundary part (between lines) of each line at one of the lower heights. , so there is a problem that the expected printing result cannot be obtained.

Sometimes an image is printed across multiple lines. In this case, in the case where font data and image data are included in one line and the character height is higher than the image data height, the printed result of one image will be broken due to blanks (white stripes) for feeding paper between lines , there is a problem that the aesthetics of the printed result deteriorates.

Contents of the invention

In view of the above-mentioned problems, an object of the present invention is to provide a printing device and a control method of the printing device that can print a plurality of lines including font data and image data in one line, so that no gaps can occur at the boundaries of the lines. way to print.

The printing device of the present invention is a printing device that can be connected to a control device, and is a printing device that prints on a printing medium in line units based on data received from the control device. The font data corresponding to the character code included in the data; the judging part, which judges whether both the character code and at least a part of the image data are included in the data of one line; To compare the character height of the font data corresponding to the character code with the image data height of the at least part of the image data when the data for one line includes both the character code and at least a part of the image data; an adjustment unit that adjusts so that the character height and the image data height become the same when it is determined that the height of the character is different from the height of the image data as a result of the comparison by the comparison unit; The font data and at least a part of the image data are printed for one line.

In addition, the control method of a printing device of the present invention is a control method of a printing device connectable to a control device, wherein the printing device prints on a printing medium in line units based on the data received from the control device, and stores and includes in the data The font data corresponding to the character code in the above-mentioned printing device is characterized in that the following steps are performed: a determination step, determining whether the above-mentioned data of one line contains both the character code and at least a part of the image data; the comparison step, As a result of the determination in the determination step, when it is determined that both the character code and at least part of the image data are included in the data for one line, the character height of the font data corresponding to the character code and the at least part of the image The height of the image data of the data is compared; the adjustment step is to adjust the height of the character and the height of the image data to be the same when the result of the comparison in the comparison step is determined to be different from the height of the character; and the printing processing step is based on The font data adjusted in the adjustment step and at least a part of the image data are used to print one line.

According to this configuration, when printing both characters (character images based on font data) and images (images based on image data) in one line, and the character height of the font data corresponding to the character to be printed and the height of the image data If the heights (image data heights) are different, they are adjusted so that both heights are the same, and printing is performed. As a result, when the print data is divided into multiple lines and printed on a line-by-line basis, in particular, image data can be printed without gaps (white stripes) occurring at the boundaries of each line, and as a result, the user can obtain The expected printing result.

In addition, as a method of adjusting the character height and image data height to be the same, there are a method of shortening one height to make both heights the same, a method of extending one height so that both heights are the same, and a method of making one height the same. A method of shortening and raising the height of the other to make both of them the same height, etc.

In addition, the character code mentioned here means: a character code indicating a character or a mark (including blank space), not a character code indicating a specific command such as line feed (character code of a control system).

In the printing apparatus according to the present invention, it is preferable that, when the result of the comparison by the comparison unit determines that the height of the character is higher than the height of the image data, the adjustment unit deletes part of the font data to be adjusted for the height of the character so that the height of the character is equal to the height of the image data. The image data height becomes the same.

According to this configuration, the height of the image data is used as a reference (priority), and the character height is shortened so that the character height and the image data height become the same. For example, in the case of character height>image data height, if the height of the image data is increased (extended) to match the height of the character by repeating part of the image data, etc., the gap at the boundary of each line can be eliminated, but Since the image printed based on the image data is printed slowly, the appearance of the printed result is impaired. In the present invention, by adjusting with the image data height as a reference (that is, by not changing the image data height), it is possible to eliminate the gap at the boundary portion of each row without impairing the appearance of the image.

Preferably, in the printing device of the present invention, when the font data is font data including at least one of an upper margin portion and a lower margin portion in the character height direction, the adjustment unit deletes the upper margin portion and the lower margin portion in the character height direction. At least one part of the margin portion is used to shorten the character height so that the character height becomes the same as the image data height.

According to this configuration, when adjusting the character height of font data, it is possible to provide various deletion methods such as a method of deleting upper and lower margins of font data, a method of deleting only upper margins, and a method of deleting only lower margins. Since the margin portion without dots in actual printing for displaying the characters contained in the font data is discriminated and deleted, the information required for user identification can be printed as characters without damaging the printing result, and the printing result expected by the user can be obtained. .

In the printing device of the present invention, when deleting the upper margin and the lower margin of the font data, it is preferable that the adjusting unit changes the deletion ratio of the upper margin and the lower margin according to the type of the font data.

According to this configuration, by either deleting the upper and lower margin parts of the font data equally, or deleting the upper margin part slightly more than the lower margin part, or deleting the lower margin part slightly more than the upper margin part, etc., it is possible to adjust the characters in the same line. It is possible to provide various deletion methods according to the type of font data to be adjusted in character height.

In the printing apparatus according to the present invention, it is preferable that the adjustment unit deletes the upper margin portion of the font data by changing the read address of the storage unit in which the font data is stored, and reduces the paper feeding amount of the printing medium accompanying the printing of the font data. Deletes the lower margin of the font data.

According to this configuration, since the upper and lower margins of the font data are deleted by changing the address for reading the font data stored in the order of addresses in the storage unit, when changing a line, and adjusting the amount of paper feeding between lines, Therefore, it can be implemented simply and without affecting the performance of the printing device.

In the printing device of the present invention, preferably, the printing device further includes a decoration presence/absence determination unit, and the decoration presence/absence determination unit receives a command related to a decoration related to a character code (font data corresponding to the character code) or The setting of the device body determines whether decoration is implemented, and the adjustment unit does not adjust the character height of the font data corresponding to the character code when it is determined by the decoration presence/absence determination unit that the decoration related to the character code is implemented. Adjustment.

According to this configuration, the character to be decorated is printed without adjusting the character height of the font data. Generally, when decorating a character, the character itself has a special intention or meaning and is printed for the purpose of providing specific information for the user in many cases. That is, the appearance of characters is important. Therefore, if the character height of the character to be decorated is adjusted, even if margins are adjusted, there is a high possibility that the balance will be lost and the appearance of the character will be damaged. As a result, the user may not be able to correctly provide specific information. In order to avoid such a situation, in the present invention, by not adjusting the character height of the font data of the characters to be decorated, it is possible to avoid impairing the appearance of the characters (decorative characters) printed for the purpose of providing information. Print below.

In addition, the decoration of characters refers to emphatic printing of characters, enlarged printing such as vertically enlarged printing, horizontally enlarged printing, reduced printing, underlined printing, strikethrough printing, designated italic font, etc. , thin font printing, black and white reverse printing, printing of the color of the specified characters and the color of the background, etc. These can be determined by whether or not there is a command for specifying the character decoration related to the character, and whether or not there is setting of a memory switch or the like.

In the printing device of the present invention, preferably, the printing device further includes a conveying unit that conveys the printing medium, the direction of the line to be printed is a direction intersecting the direction in which the printing medium is conveyed by the conveying unit, and the height of the characters and the height of the image data are is the direction in which the printing medium is conveyed.

According to this configuration, it can be applied to a printing apparatus equipped with a serial head and a printing apparatus equipped with a line head.

Detailed ways

Hereinafter, a printing device and a method of controlling the printing device according to an embodiment of the present invention will be described with reference to the drawings. In addition, in this embodiment, a printing system composed of a printing device and a host device cooperating with the printing device will be described as an example.

Fig. 1 is a control block diagram of the printing system SY of the present invention. As shown in FIG. 1 , the printing system SY according to this embodiment is composed of a printing device 1 that performs printing processing based on data, and a host device 2 (control device) that generates data and transmits the data to the printing device 1 .

In addition to CPU11 (Central Processing Unit), ROM12 (Read OnlyMemory), RAM13 (Random Access Memory), HDD14 (Hard Disk Drive), and interface unit 15, the host device 2 also has a hardware configuration mounted on a general personal computer.

The ROM 12 stores control programs and control data for executing various processes by the CPU 11 . In addition, RAM 13 is used as a work area when CPU 11 executes various processes. The interface unit 15 transmits and receives data to and from the printing device 1 .

An application program 14a for printing characters and images is stored in HDD 14 . The CPU 11 executes a print command based on the application program 14 a, and transmits data to the printing device 1 via the interface unit 15 . In addition, this data includes character codes, graphic data, commands for control (including commands related to character decoration), and the like.

The printing device 1 includes a CPU 21 , a ROM 22 , a RAM 23 , a character generator ROM 24 (CG-ROM 24 , storage unit), an interface unit 25 , a printing unit 26 , and a transport unit 27 , and these components are connected to each other by an internal bus 28 .

The interface unit 25 is used to connect to the host device 2 and receive data from the host device 2 via the interface unit 25 . The received data is stored in the print buffer 34 via the receive buffer 33 described later.

The printing unit 26 uses the print head 35 as a main part, and drives the print head 35 to print font data and images of symbols such as characters and symbols in units of lines based on the print image stored in the print buffer 34 described later (image data based on the image data). image) printing. The transport unit 27 has the paper feed roller 36 as a main part, and drives the paper feed roller 36 to feed (transport) the printing medium in synchronization with the printing operation by the print head 35 .

In addition, the print head 35 of this embodiment may be constituted by a serial head, or may be constituted by a line head. When the printing head 35 is constituted by a serial head, after the printing of one line is completed by the printing head 35 , the paper feeding roller 36 is driven to feed the printing medium. On the other hand, when the print head 35 is constituted by a line head, the paper is fed by driving the paper feed roller 36 and printing is performed for each dot line, thereby performing printing for one line.

The CG-ROM 24 stores font data of symbols such as characters and symbols, and outputs the corresponding font data when a predetermined character code is given.

The RAM 23 has a receive buffer 33 for temporarily storing data received from the host device 2 in addition to a work area block 32 used when the CPU 21 executes various processes, and stores print images (print data) in line units for actual printing. ) of the print buffer 34. The data stored in the receiving buffer 33 is processed line by line by a height adjustment program 31 described later, and the processed print image is stored in the print buffer 34 in units of lines.

The ROM 22 stores control programs and control data for the CPU 21 to perform analysis of various commands and various processes. Specifically, the height adjustment program 31 is included as a control program. The height adjustment program 31 is in the case where both character codes and image data are included in the data for one line (that is, when printing symbols (characters, symbols, etc.) and images corresponding to the character codes in one line), the program follows the The height of the font data corresponding to the character code (the number of dots in the direction of the printing medium on which the font data is conveyed (hereinafter referred to as "character height")) and the height of the image data (the number of dots in the direction of the printing medium that conveys the image data. The following , referred to as "image data height".) The procedure for adjusting in the same way (details will be described later).

In addition, the character code included in the data may be used for printing characters for the purpose of providing some information to the user (hereinafter referred to as "normal characters"), and may be used for printing based on image data. The position adjustment of the printed image (adjustment of the printing position of the image on the printing medium) is the case of the intended character (hereinafter, referred to as "position adjustment character"), wherein the above-mentioned height adjustment procedure is executed in the latter case 31 processing.

Next, functions provided by the printing apparatus 1 will be described with reference to FIGS. 2 and 3 . FIG. 2 is a functional block diagram of the printing apparatus 1, and FIG. 3 is an image diagram (conceptual diagram) for explaining a method of deleting part of font data.

As shown in FIG. 2 , the printing apparatus 1 includes: a data receiving unit 41, a data judging unit 42 (judging unit), a height comparing unit 43 (comparing unit), a decoration determination unit 44, a height adjusting unit 45 (adjusting unit), and a print processing unit 46 . Among them, the data determination unit 42 , the height comparison unit 43 , the decoration presence/absence determination unit 44 , and the height adjustment unit 45 have the height adjustment program 31 as a main part.

The data receiving unit 41 has the interface unit 25 as a main part, receives data from the host device 2 , and stores the received data in the receiving buffer 33 .

The data judging unit 42 reads data from the receiving buffer 33 in units of one line, and judges whether or not both character codes and image data (at least a part of the image data) are included in the data of the line. In addition, the division of one line can be judged by the number of data that can be printed in one line and the reception of a code indicating line break or the like.

When the result of the determination by the data determination unit 42 is that both the character code and the image data are included in the data for one line, the height comparison unit 43 refers to the font data corresponding to the character code, and the character of the font data The height is compared with the height of the image data (image data height).

When the result of the comparison by the height comparison unit 43 is that the height of the character is higher than the height of the image data (in the case of the height of the character>the height of the image data), the decoration presence/absence determination unit 44 determines whether or not the decoration related to the character code is received. Related control commands (hereinafter, referred to as "decoration commands"). When a decoration instruction is received, the font data corresponding to the character code is judged as "normal character", and when the decoration instruction is not received, the font data corresponding to the character code is judged as "position adjustment character". ".

In the case of character height>image data height and no decoration instruction is received (that is, when the font data is determined to be a "position adjustment character"), the height adjustment unit 45 deletes the upper part of the character height direction of the font data. A part of the margin portion and the lower margin portion so that the character height of the font data becomes the same as the height of the image data.

The printing processing unit 46 has the printing unit 26 and the conveying unit 27 as main parts, generates a printed image for one line based on the font data and image data adjusted by the height adjusting unit 45, and controls the printing unit 26 and the conveying unit 27 to execute Printing of printed images.

Here, for the sake of easy understanding, the deletion of the upper and lower margin portions of font data performed by the height adjustment unit 45 will be described using the image diagram of FIG. 3 . FIG. 3( a ) is an image diagram showing a state in which font data and image data printed in one line have different heights. Here, it is assumed that the character height of the font data is 27 dots, and the image data height of the image data is 24 dots. That is, since the character height of the font data is 3 dots higher than the height of the image data, the height adjustment unit 45 deletes (shortenes) the character height of the font data by 3 dots.

This deletion process is performed by deleting a total of 3 dots of the upper margin portion 51 and the lower margin portion 52 of the font data, as shown in FIG. 3( b ). FIG. 3( b ) shows a state in which one dot of the upper margin portion 51 is deleted and two dots of the lower margin portion are deleted.

The deletion of the upper margin portion 51 is realized by changing the head address when the font data is read from the CG-ROM 24 . That is, it is realized by changing the head address when reading the font data to an address one dot ahead in the character height direction than usual.

On the other hand, the deletion of the lower margin portion 52 is realized by adjusting the paper feeding amount. That is, it is realized by controlling the paper feeding by the conveyance unit 27 (paper feed roller 36 ) so that the paper feed amount is reduced by 2 dots (2 dots in the character height direction). By performing the deletion process in this way, as shown in FIG. 3( c ), it is adjusted so that the character height of the font data and the image data height of the image data become the same (here, 24 dots).

In addition, as shown in FIG. 3( b ), the method of deleting one point of the upper margin portion 51 and deleting two points of the lower margin portion 52 is an example. For example, two points of the upper margin portion 51 may be deleted, and the lower margin portion 52 to delete 1 point. In addition, the deletion ratio of the upper and lower margin portions 51 and 52 can be changed for each type of font data to be targeted. Alternatively, the deletion ratio of the upper and lower margin portions 51 and 52 is fixed regardless of the type of font data. In addition, in FIG. 3, the case where font data for one character exists in one line has been described, but this is an example, and by performing the same process even when there is a plurality of font data, it is possible to make the characters of the font data The height matches the image data height.

Next, the printing processing procedure of the printing apparatus 1 will be described with reference to the flowchart of FIG. 4 . First, the CPU 21 (printing device 1) receives data from the host device 2 and stores it in the receiving buffer 33 (S01). Next, CPU 21 acquires data for one line from receiving buffer 33 (S02), and determines whether the data for one line includes both character codes and image data (at least a part of image data) (S03: determination step).

When the result of the determination in S03 is that only one of character codes and image data is included in the data for one line, that is, when the data for one line is composed of only character codes or only image data (S04 : No), the CPU 21 generates a print image (print data) based on the font data or image data corresponding to the character code, and prints based on the print image (S10). That is, in this case, normal printing processing is performed without performing height adjustment of font data or image data.

On the other hand, when the result of the determination in S03 is that both the character code and the image data are included in the data for one line (S04: Yes), the CPU 21 compares the character height of the font data corresponding to the character code and the The image data heights of the image data are compared (S05: comparison step).

When the result of the comparison in S05 is that the character height is equal to or less than the image data height (in the case of character height≦image data height, S06: No), the CPU 21 generates a printed image based on the font data and image data corresponding to the character code. image, and the height of the image data is used as a reference to determine the paper feeding amount, thereby executing printing (S10).

On the other hand, when the result of the comparison in S06 is that the character height is higher than the image data height (in the case of character height>image data height, S06: YES), CPU 21 determines whether the data of one line contains the character code. Involved decorator instruction (S07).

When it is determined in S07 that the decoration command is included (S08: Yes), the CPU 21 determines that the font data corresponding to the character code is to be printed as a "normal character", and based on the font data and image data corresponding to the character code and a decoration command to generate a print image, determine the amount of paper feeding based on the character height of the font data, and execute printing (S10).

On the other hand, when it is determined in S07 that the decoration command is not included (S08: No), the CPU 21 determines that the font data corresponding to the character code is a "position adjustment character", and executes the font data corresponding to the character code. The deletion process of the upper margin portion 51 and the lower margin portion 52 of the data is adjusted so that the character height of the font data and the image data height of the image data become the same. In other words, the height of the image data is prioritized (as a reference), and processing of matching the character height of the font data with the height of the image data is performed ( S09 : adjustment step). Then, the CPU 21 generates a print image for one line based on the font data and image data adjusted in S09 , and controls the printing unit 26 and the transport unit 27 to print based on the print image ( S10 : printing processing step). In addition, the CPU 21 repeatedly executes the processing of S01 to S10 until there is no more data to be printed.

As described above, according to this embodiment, when the data for one line includes both character codes and image data, and the character height of the font data corresponding to the character code to be printed and the height of the image data (image data height) are different, adjust the height of both to be the same and print. As a result, when data is divided into multiple lines and printed in line units, printing can be performed without gaps (white stripes) appearing at the boundaries of the lines, and as a result, printing results expected by the user can be obtained.

In addition, in this embodiment, as a method of adjusting the character height and the image data height to be the same, a method of shortening the character height to be the same as the image data height is exemplified, but the present invention is not limited thereto. For example, the adjustment may be made so that the height of the image data is increased to be the same as the height of the characters, or the height of the characters is shortened and the height of the image data is increased to be the same.

In addition, in the present embodiment, a method of deleting both the upper margin portion 51 and the lower margin portion 52 of the font data is described when adjusting the character height of the font data, but the present invention is not limited thereto. For example, only the upper margin portion 51 of the font data may be deleted to adjust the character height, or only the lower margin portion 52 of the font data may be deleted to adjust the character height. Accordingly, it is possible to appropriately adjust the balance of the positions of characters in the same line.

In addition, in this embodiment, the procedure for performing height adjustment when the relationship of character height>image data height is satisfied is described, but it is not limited to this, and height adjustment may be performed when character height<image data height . In this case, the character height can be increased to match the image data height, or the image data height can be shortened to match the character height. Alternatively, it is also possible to adjust in such a way that the character height is increased and the image data height is shortened so that both are the same.

In addition, in this embodiment, character decoration is realized by a decoration command, but it is not limited to this. For example, it can also be applied to a device having a function of embellishing characters by setting a dip switch, a memory switch, etc. (both not shown) of the main body of the printing device 1 . In this case, the decoration presence/absence determination unit 44 checks the setting states of the DIP switch and the memory switch to determine the presence or absence of the character decoration.

In addition, in the present embodiment, when there is a decoration command related to a character code in the data, it is determined that the font data corresponding to the character code is used as a "position adjustment character", and the height adjustment unit 45 performs processing, but is not limited to this. For example, when the character code included in the data is a specific character code (for example, a character code indicating a space and a character code indicating a mark), the font data corresponding to the character code may be determined as "position adjustment". character" and perform processing based on the height adjustment unit 45.

In this case, the height adjustment unit 45 may analyze the font data, determine and delete a margin portion of data without dots for displaying characters included in the font data. Accordingly, information required for user identification can be printed as characters without deteriorating the printing result, and a printing result desired by the user can be obtained.

In addition, in this embodiment, an example in which the row direction intersects the paper feeding direction has been described, but it can also be applied to a case where printing is performed for each page. In this case, the area of the print buffer 34 is defined as a page, and the font data and image data are arranged and stored at specified positions within the page area of the print buffer 34 as a print image in units of lines. Since lines including font data and image data can be arranged in any direction within the page area, they can be arranged in a direction intersecting the line direction and the paper feeding direction for printing as in this embodiment, and can also be arranged in Printing is performed in a direction parallel to the line direction and paper feed direction. Like the latter, even if the row direction and the paper feeding direction are parallel directions, as described in the above-mentioned embodiment, it is only necessary to delete margins of the font data and arrange them in the page area, so the same row can be adjusted. The height of the font data and the height of the image data.

In addition, it does not depend on the above-described embodiments, and the device configuration and processing steps of the printing system SY, and the device configuration, processing steps, and control method of the printing device 1 can be appropriately changed without departing from the gist of the present invention. .
