Abstract
A printing apparatus sequentially prints a plurality of images on a first surface of a sheet, and then sequentially prints a plurality of images on a second surface that is a back surface of the first surface. When a state of a printing unit is determined not to be normal when printing on the first surface, the printing apparatus executes processing for maintenance by using a sheet different from the sheet used for printing on the first surface.
Claims14
A printing control apparatus comprising:
- a printing control unit configured to cause a printing unit to sequentially print a plurality of images on a first surface of a sheet and to cause the printing unit to sequentially print a plurality of images on a second surface of the sheet that is a reverse side of the first surface, after the printing of the plurality of images on the first surface is performed;
- and
- a maintenance processing unit configured to execute a processing for maintenance of the printing unit by performing a printing for maintenance on a sheet, in a case where a state of the printing unit is determined as not normal,
- wherein, in a case where a state of the printing unit is determined as not normal before performing a printing to the second surface of the sheet, the printing control unit supplies another sheet other than the sheet on which images are printed on the first surface and the maintenance processing unit executes a processing for maintenance to said another sheet being supplied, and the printing control unit supplies the sheet on which images are printed on the first surface after the processing for maintenance is executed, and prints the images on the second surface corresponding to the images which are normally printed within the plurality of images printed on the first surface of the sheet.
The printing control apparatus according to claim. 1, wherein an image for proof inspection is printed after executing the processing for maintenance.
The printing control apparatus according to claim. 6, wherein the image for proof inspection is printed in an area that is a second surface of a sheet of which images are printed on a first surface and corresponding to images which are not normal within a plurality of images printed on a first surface.
A printing control method comprising:
- sequentially printing a plurality of images on a first surface of a sheet;
- sequentially print a plurality of images on a second surface of the sheet that is a reverse side of the first surface, after printing the plurality of images on the first surface;
- and
- performing a processing for a maintenance of the printing unit by executing a printing for maintenance on a sheet, in a case where a state of the printing unit is determined as not normal,
- wherein, in a case where a state of the printing unit is determined as not normal while printing images on the first surface of the sheet, the processing for maintenance is executed by supplying another sheet other than the sheet on which images are printed on the first surface is supplied, and after the processing of maintenance is executed, the sheet on which images are printed on the first surface is supplied, and imaged on the second surface corresponding to the images printed normally within a plurality of images printed on the first surface are printed.
