Abstract
In a case that it is determined that a first feeding unit is not ready to feed upon designation of a first print job that requires air feeding, start of the first print job is waited until the first feeding unit is ready to feed. In a case that a second print job that requires roll feeding is accepted during waiting for the first print job, the second print job is executed, and the first print job that requires air feeding is executed after completion of the second print job.
Claims9
A printing apparatus comprising:
- a first feeding unit configured to separate a sheet from other sheets using air and to feed the sheet;
- a second feeding unit configured to feed a sheet using a roller;
- an accepting unit configured to accept a first print job for printing an image on the sheet fed from the first feeding unit and a second print job for printing an image on the sheet fed from the second feeding unit;
- a determination unit configured to determine whether the first feeding unit can feed the sheet existing in the first feeding unit or the first feeding unit cannot feed the sheet existing in the first feeding unit;
- and
- a control unit configured to execute, in a case where the determination unit determines that the first feeding unit cannot feed the sheet existing in the first feeding unit, the second print job accepted after accepting the first print job, prior to executing of the first print job.
A method of controlling a printing apparatus which comprises a first feeding unit configured to separate a sheet from other sheets using air and to feed the sheet, and a second feeding unit configured to feed a sheet using a roller, the method comprises;
- accepting a first print job for printing an image on the sheet fed from the first feeding unit and a second print job for printing an image on the sheet fed from the second feeding unit;
- determining whether the first feeding unit can feed the sheet existing in the first feeding unit or the first feeding unit cannot feed the sheet existing in the first feeding unit;
- and
- executing, in a case where it is determined that the first feeding unit cannot feed the sheet existing in the first feeding unit, the second print job accepted after accepting the first print job, prior to executing of the first print job.
A non-transitory computer-readable medium storing a computer program for causing a computer to execute a method for controlling a printing apparatus which comprises a first feeding unit configured to separate a sheet from other sheets using air and to feed the sheet, and a second feeding unit configured to feed a sheet using a roller, the computer program comprises;
- a code to accept a first print job for printing an image on the sheet fed from the first feeding unit and a second print job for printing an image on the sheet fed from the second feeding unit;
- a code to determine whether the first feeding unit can feed the sheet existing in the first feeding unit or the first feeding unit cannot feed the sheet existing in the first feeding unit;
- and
- a code to execute, in a case where it is determined that the first feeding unit cannot feed the sheet existing in the first feeding unit, the second print job accepted after accepting the first print job, prior to executing of the first print job.
