Printing apparatus and method for controlling printing apparatus

A printing apparatus comprising:

• transport means for transporting a print medium along a transport path;
• printing means for printing on the print medium at a predetermined print position in the transport path;
• discharge means for discharging the print medium from the transport path;
• and
• double-sided printing control means for controlling the transport means, the printing means and the discharge means to execute a double-sided printing to print on a first surface and a second surface of the print medium;
• wherein, the double-sided printing control means controls the transport means, the printing means and the discharge means so that, when the printing of a last page of print data based on a preceding print job is ended on the first surface of a print medium, the double-sided printing control means (1) controls the discharge means so as not to discharge the print medium, and to hold the print medium, whose first surface was printed, in the transport path and, (2) when a next print job is input, controls the printing means to print a first page of print data from the next print job on the second surface of the print medium held in the transport path.

A method for controlling a printing apparatus, wherein the printing apparatus includes:

• transport means for transporting a print medium along a transport path;
• printing means for printing on the print medium at a predetermined print position in the transport path;
• discharge means for discharging the print medium from the transport path;
• and
• double-sided printing control means for controlling the transport means, the printing means and the discharge means to execute a double-sided printing to print on a first surface and a second surface of the print medium;
• the printing apparatus control method comprising the step of:
• selecting one of a plurality of modes, including a first mode and a second mode, to execute the double-sided printing;
• wherein the first mode is a mode in which all print mediums that have been printed according to a print job are discharged by the discharge means;
• wherein the second mode is a mode in which, when the printing of a last page of print data from a first print job is ended on the first surface of a print medium, the print medium whose first surface was printed is not discharged by the discharge means and is held in the transport path to wait for an input of a second print job, and a first page of print data from the second print job is printed on the second surface of the print medium held in the transport path.

• printing means for printing on the print medium at a predetermined print position in the transport path;
• discharge means for discharging the print medium from the transport path;
• and
• double-sided printing control means for controlling the transport means, the printing means and the discharge means to execute a double-sided printing to print on a first surface and a second surface of the print medium;
• the printing apparatus control method comprising the step of:
• controlling the transport means, the printing means and the discharge means by the double-sided printing control means so that when the printing of a last page of print data of a first print job is ended on the first surface of a print medium, the print medium whose first surface was printed is not discharged by the discharge means but is held in the transport path to wait for an input of a second print job, and print data of the second print job is printed on the print medium held in the transport path.
