Abstract
Images are sequentially printed on a first surface of a sheet, and identification information for identifying an image is formed each time an image is printed. When printing is interrupted by the error and before resuming printing, the identification information formed on the first surface of the sheet fed from the reverse unit again is read by the reader, and an image to be printed on the second surface when resuming printing is specified based on the read identification information.
Claims13
An apparatus for duplex printing comprising:
- a sheet feeding unit configured to feed a continuous sheet;
- a printing unit configured to perform printing on the sheet;
- a reverse unit configured to reverse the sheet for the duplex printing;
- a reader configured to read identification information formed on the sheet;
- and
- a control unit,
- wherein the control unit controls the apparatus such that,
- the printing unit prints a plurality of images and identification information for identifying each of the images, on a first surface of the sheet fed from the sheet feeding unit,
- the reverse unit stores the sheet printed on the first surface and feeds the reversed sheet to the printing unit,
- the printing unit prints a plurality of images on a second surface that is a back of the first surface of the sheet fed from the reverse unit, and,
- when printing is interrupted by an error and before resuming printing, the reader reads the identification information formed on the first surface of the sheet fed from the reverse unit, and the control unit specifies an image to be printed on the second surface for resuming based on the read identification information.
