Abstract
An object of this invention is to provide a job processing method for a convenient printing system applicable not only to the office environment but also to the POD environment, a storage medium, a program, a printing system, and a printing apparatus. To accomplish this, according to a job processing method for a printing system in which print media detected by a multi feed detection unit for detecting occurrence of multi feed of overlapping print media can be used as print media necessary for a job to be processed by a printing apparatus, when multi feed occurs, the printing system can execute a recovery operation for an unprinted job without outputting multi-fed print media to a print medium discharge destination necessary for the unprinted job in the printing system.
Claims7
A printing system comprising:
- a discharging controller adapted to cause a discharger to perform a discharging operation for discharging overlapping sheets supplied from a supplier without supplying the overlapping sheets to a printer, presence of the overlapping sheets being checked by a checker while the printer performs a printing operation using non-overlapping sheets supplied from the supplier;
- and
- a printing controller adapted to cause the printer to continue the printing operation in response to the discharging operation performed by the discharger.
A program product stored in a computer usable storage medium, the program product including a program code for causing a computer system to perform a method, the method comprising:
- causing a discharger to perform a discharging operation for discharging overlapping sheets supplied from a supplier without supplying the overlapping sheets to a printer, presence of the overlapping sheets being checked by a checker while the printer performs a printing operation using non-overlapping sheets supplied from the supplier;
- and
- causing the printer to continue the printing operation in response to the discharging operation performed by the discharger.
