Description

  The present invention relates to an image processing system, and more particularly to an image processing system capable of proxy printing, an image processing method, and a printer apparatus.

  Conventionally, as this type of system, for example, in an automatic transaction system, a failure detection unit provided in an automatic transaction apparatus detects a printing failure of a usage statement slip. There is one that requests proxy printing from a general-purpose terminal, and this general-purpose terminal performs proxy printing of the usage statement slip based on the print data necessary for printing the usage statement slip set in the request (for example, patent document) 1).

JP-A-5-165870 (first page, FIG. 1)

  In such a system, since the printing process for proxy printing is performed based on print data determined to some extent, if a general-purpose terminal capable of handling this printing process is prepared, problems in the printing process will not occur. However, it cannot cope with printing in which printing conditions such as resolution and paper size are variously set, such as image data.

  An object of the present invention is to perform printing on behalf of a printer designated for printing when performing proxy printing for printing in which printing conditions such as resolution and paper size are variously set, such as image data. An image processing system, an image processing method, and an image processing system in which printing can be performed promptly by another printer capable of printing that meets conditions even when printing cannot be performed due to out of paper or failure To provide a printer device.

An image processing system according to the present invention includes an upper-level device, a first printer, a second printer, and a communication unit that connects the higher-level device, the first printer, and the second printer to a network. In the processing system,
The host device transmits image data for printing to the first printer, and the first printer determines whether the image data from the host device is printable and determines that printing is not possible. If it is determined, second printer information indicating printer performance is acquired from the second printer via the communication means, and the image data including the second printer information is transferred to the second printer. Notification information for inquiring whether to perform printing is transmitted to the host device, and when the first printer receives the proxy printing instruction information from the host device, the image data from the host device is transmitted. Is transmitted to the second printer via the communication means, and the second printer performs proxy printing of the image data from the first printer ,
The host device displays proxy influence information indicating an influence of a printing condition when the proxy printing is performed on a print result .

  Even when the printer designated for printing is in a state incapable of printing, the proxy printing can be performed by another printable printer, so that the printing process can be performed smoothly. Moreover, since there is no restriction that the printers must be the same between these printers, the printer is also excellent in terms of the degree of freedom when configuring the system.

  With the above configuration, the operation of the image processing system 1 will be described below.

In this example, the driver 12 of the host device 2 includes the first printer 3 and the second printer 2 including the printers to be substituted based on the substitution information (FIG. 6) described later saved in the substitution information saving unit 14. Print data including image data that can be interpreted by each of the printers 4, size information of the image data, and printing condition information that defines printing conditions in each of the first printer 3 and the second printer 4 is created. The printing conditions include information such as whether the data is data for printing, the resolution of the printer to print, the size of the paper on which the image data is printed, whether to print in color or monochrome, and so on. . FIG. 6 is an explanatory diagram showing the contents stored by the proxy information storage unit 14 of the higher level apparatus 2. As shown in FIG. 6, the proxy information storage unit 14 stores the print designation destination selected by the higher level apparatus 2. The printer type is stored in correspondence with the priority order. Note that the transmission / reception unit 13 of the host device 2, the transmission / reception unit 21 of the first printer 3, the transmission / reception unit 31 of the second printer 4, and the network 5 constitute communication means for network connection to each other.

  When the driver 12 starts creating print data, the driver 12 obtains print designation destination information (FIG. 6) saved in the proxy information saving unit 14 and obtains information on a printer that needs to create image data (step S101). . Next, the driver 12 creates image data (step S102), and calculates the size of the created image data (step S103). Finally, print data having the structure described with reference to FIG. 5 is created based on the created image data and their sizes (step S104).

  When the creation of print data by the driver 12 is completed, the host device 2 transmits the print data from the transmission unit 13 to the first printer 3 via the network 5 (FIG. 1). FIG. 8 is a flowchart showing an operation procedure of print data reception processing executed by the first printer 3 upon receiving print data at this time. Hereinafter, the print data receiving process executed by the first printer 3 will be described with reference to this flowchart.

  When the transmission / reception unit 21 receives print data, the first printer 3 shown in FIG. 3 determines whether the data received by the determination unit 22 is data for printing (step S111). If it is determined that the received data is not print data, the print data reception process is terminated. When determining whether or not the received data is data for printing, as shown in FIG. 5, “data type” information included in the printing condition information of the first printer 3 included in the print data is used. If the received data is data for printing, the determination unit 22 determines whether the print data received by the first printer 3 can be printed (step S112). Here, it is checked whether the first printer 3 satisfies the printing conditions required for the first printer included in the print data, whether there is printing paper, or whether the apparatus is out of order. If printing is possible, the determination unit 22 extracts image data and detailed information for use in the first printer 3 from the print data and transmits them to the printing unit 24 (step S113). The printing unit 24 receives the input data. Interpreted and printed (step S119).

  If the determination unit 22 determines that printing of the print data received by the first printer 3 is impossible, the received print data is stored in the transfer data storage unit 26 as it is (step S114), and neighboring printer information is stored. The neighboring printer information stored in the storage unit 27 is updated (step S115).

  FIG. 9 is a flowchart showing a procedure for updating neighboring printer information performed in step S115. As shown in this flowchart, when the neighboring printer information update is started, the neighboring printer information acquisition unit 23 sends an information acquisition packet for requesting printer information to the network (step S115a). Thereafter, it waits for a predetermined time until there is a response from the neighboring printer (step S115b). Thereafter, the responses up to the elapse of a predetermined time are aggregated by the neighboring printer information acquisition unit 23 to create neighboring printer information, stored in the neighboring printer information storage unit 27, and the data is updated (step S115c). End the flow.

  FIG. 10 is a flowchart for explaining processing executed by the second printer 4 shown in FIG. 1, which is a neighboring printer, at this time upon receiving the information acquisition packet sent by the first printer 3. As shown in this flowchart, when the second printer 4 receives the information acquisition packet from the first printer 3, the printer information acquisition unit 34 (FIG. 4) determines whether it can respond (step S121). If no response is possible, the flow ends without responding. If a response is possible, the printer information is collected (step S122), communication data is created, and the communication data is transmitted to the requester of the neighboring printer information, that is, the first printer 3 (step S123). End the flow.

  As described above, when the neighboring printer information update in step S115 (FIG. 8) by the first printer 3 (FIG. 3) is completed, the neighboring printer information acquisition unit 23 (FIG. 3) of the first printer 3 Information on neighboring printers that can perform proxy printing is acquired from the storage unit 27 (S116), and the notification information creation unit 25 provides notification information for notifying the host device 2 that the first printer 3 cannot be printed. The neighboring printer information is obtained and created (S117).

  FIG. 11 is an explanatory diagram showing the contents of the notification information at this time. The notification information includes information indicating that the first printer 3 that first received the print instruction cannot be printed, as well as printer information of the first printer 3 as well as information indicating that the first printer 3 has received a print instruction from among neighboring printers. The printer information of the second printer 4 listed as a candidate for proxy printing is included. The contents of the printer information include “resolution”, “paper size”, “color / monochrome”, and “installed PDL (page description language)” indicating the performance of the printer. The transmission / reception unit 21 transmits the notification information created by the notification information creation unit 25 in this way to the higher-level device 2 (S118), and ends this data reception flow.

  FIG. 12 shows the notification information from the first printer 3, that is, the information that the first printer 3 cannot print, and the information of the second printer 4 that is the first printer 3 and the neighboring printer. It is a flowchart explaining the process implemented in response to a notification including. As shown in this flowchart, when the host device 2 receives the notification information from the first printer 3, the notification information analysis unit 15 (FIG. 2) analyzes the message notified (step S131), and the analysis result is displayed on the display. It is displayed on the part 16 (step S132).

  FIG. 13 is an explanatory diagram showing a notification information display screen 41 displayed on the display unit 16 at this time. The notification information display screen 41 indicates that the first printer 3 cannot print, discloses the printer information of each printer, and can also be printed by the second printer 4. A message is displayed asking for an instruction to execute or not.

  Thereafter, while watching the notification information display screen 41, it is monitored that the user inputs a proxy printing permission / inhibition command using the external I / F unit 17 (FIG. 2) (step S133). Eventually, when the user inputs a proxy printing permission / inhibition command, the selection information creation unit 18 creates user selection notification information for notifying the first printer 3 of the selection result based on the permission / inhibition command (step S134). The transmission / reception unit 13 transmits the user selection notification information to the first printer 3 (step S135), and ends this flow.

  FIG. 14 is a flowchart illustrating a process in which the first printer 3 receives and executes the above-described user selection notification information from the higher-level device 2. As shown in this flowchart, when the transmission / reception unit 21 of the first printer 3 shown in FIG. 3 inputs user selection notification information from the higher-level device 2, the determination unit 22 analyzes the user selection notification information data and performs proxy processing. It is determined whether printing is permitted (step S141). If not permitted, the data stored in the transfer data storage unit 26 is deleted (step S144), and the process ends. If the proxy printing is permitted, the print data stored in the transfer data storage unit 26 is extracted (step S142), and the print data is transmitted to the second printer 4 (step S143), and the process is terminated.

  FIG. 15 is a flowchart for explaining processing that the second printer 4 receives and executes print data from the first printer 3. As shown in this flowchart, when the second printer 4 shown in FIG. 4 receives print data, the transmission / reception unit 31 determines whether the received data is print data (step S151). If it is not data, the print data reception process is terminated. If it is data for printing, the print data analyzing unit 32 extracts image data and detailed information for use in the second printer 4 from the received print data and transmits them to the printing unit 33 (step S152). The printing unit 33 interprets and prints the input data (S153).

  In the above-described image processing system, when the first printer 3 cannot print the print data received from the upper apparatus 2, the notification information including the neighboring printer information is transmitted to the upper model 2 to perform proxy printing. An example in which user selection notification information indicating whether or not is received from the host device 2 and print data is transmitted to the second printer 4 based on the result is shown. However, the present invention is not limited to this. For example, when the first printer 3 determines that the print data received from the higher-level device 2 cannot be printed, it remains as it is or after obtaining neighboring printer information. The print data may be transmitted to the second printer 4 based on the data.

  As described above, according to the image processing system of the first embodiment, even if the printer designated for printing by the host apparatus is in an unprintable state, proxy printing can be performed by another printable printer. Therefore, the printing process can be performed smoothly. Moreover, since there is no restriction that the printers must be the same between these printers, the printer is also excellent in terms of the degree of freedom when configuring the system.

Embodiment 2. FIG.
FIG. 16 is a block diagram showing the main configuration of the signal processing system of the first printer 53 of the image processing system according to the second embodiment of the present invention. FIG. 17 shows the signals of the second printer 54 according to the second embodiment. It is a block diagram which shows the principal part structure of a processing system.

  The image processing system that employs the first printer 53 and the second printer 54 is mainly different from the image processing system 1 of the first embodiment shown in FIG. 8 is partially different from the processing contents of the first printer 3 of the first embodiment shown in FIG. 8, and the second printer 54 is different from the second printer 4 of the first embodiment shown in FIG. 32 is omitted. Accordingly, in the image processing system according to the second embodiment that employs the first printer 53 and the second printer 54, the same reference numerals are given to the parts common to the image processing system 1 (FIG. 1) of the first embodiment. Or, omitting the drawings, omitting the description here, focusing on the different points.

  18, as in the first embodiment, when print data created by the host apparatus 2 is transmitted according to the flow shown in FIG. 7, the print data is received and executed by the first printer 53. It is a flowchart which shows the operation | movement procedure of a data reception process. Hereinafter, the data reception process executed by the first printer 53 will be described with reference to this flowchart.

  When the transmission / reception unit 21 receives print data, the first printer 53 shown in FIG. 16 determines whether the data received by the determination unit 55 is data for printing (step S111). If it is determined that the received data is not print data, the print data reception process is terminated. When determining whether or not the received data is data for printing, “data type” information included in the printing condition information of the first printer 53 included in the print data is used as shown in FIG. If the received data is data for printing, the determination unit 55 determines whether the print data received by the first printer 53 can be printed (step S112). Here, it is checked whether the first printer 53 satisfies the printing conditions required for the first printer included in the print data, whether there is printing paper, or whether the apparatus is out of order. If printing is possible, the determination unit 55 extracts image data and detailed information for use in the first printer 53 from the print data and transmits them to the printing unit 24 (step S113). The printing unit 24 receives the input data. Interpreted and printed (step S119).

  If the determination unit 55 determines that printing of the print data received by the first printer 53 is impossible, it is necessary for printing the received print data in the transfer data storage unit 26 by the second printer 54. The image data and detailed information to be obtained are extracted and stored (step S214), and the neighboring printer information stored in the neighboring printer information storage unit 27 is updated (step S115). The processing contents of the first printer 53 from step S115 to step S118 and the operation of the neighboring printer involved in the steps in between are exactly the same as the processing contents of the first printer 3 of the first embodiment. Description is omitted.

  On the other hand, FIG. 19 is a flowchart for explaining a process in which the second printer 54 receives and executes storage data stored in the transfer data storage unit 26 from the first printer 53. The saved data received by the second printer 54 at this time is based on the flow of FIG. 14 described above when the first printer 53 receives the user selection notification information from the host device 2 as in the first embodiment. Thus, the stored data is extracted from the transfer data storage unit 26 and transmitted. Therefore, in the second embodiment, the stored data transmitted here is image data and detailed information necessary for printing by the second printer 54.

  As shown in this flowchart, when the second printer 54 shown in FIG. 17 receives the stored data, the transmission / reception unit 31 determines whether or not the received data is print data (step S251), and print data. Otherwise, the stored data reception process ends. If the data is for printing, the input stored data is transmitted to the printing unit 33 as it is (step S252). The printing unit 33 interprets and prints the input data (S253).

  As described above, according to the image processing system of the second embodiment, in addition to the effects of the image processing system of the first embodiment, the second printer can print the data received from the first printer as it is. Since the print data analysis unit is not required, the configuration of the second printer can be simplified, and the data processing process by the second printer can be reduced, so that the printing time can be expected to be shortened.
