There is known an inkjet recording apparatus having a structure capable of recording on roll paper and cutting the roll paper after recording at an appropriate cutting position. In such an ink jet recording apparatus, the recording execution control and the roll paper cutting control that are generally performed conventionally are performed by first recording the recording execution area on the roll paper based on the recording paper size information included in the recording data. The cutting position near the end of the recording execution area is determined. Subsequently, recording is executed in the recording execution area of the roll paper by the recording execution means, the recording paper is cut at a predetermined cutting position, and is ejected by the paper ejection means in the same manner as plain paper such as plain paper. After the cutting, the roll paper is fed back so that the starting end of the roll paper on the upstream side in the sub-scanning direction from the cutting position becomes the start position of the next print execution control, and the next print is executed.

However, when recording is continuously performed on the roll paper, the roll paper is conveyed to the cutting position in the sub-scanning direction each time recording is completed, cut, and then fed backward. If the next recording is repeated by performing the recording, the throughput of the recording is not good. Therefore, when recording is continuously performed on the roll paper, the next recording is performed without cutting the roll paper immediately after the recording is completed. Next, when the position where the roll paper should be cut reaches the cutting position of the roll paper cutting means during the next recording execution, the recording being executed is interrupted and the roll paper is cut. And
