Abstract
A printing device may include two printers for printing to the front side and the back side of a recording medium. The physical page length of at least one print image applied onto the front side of the recording medium is determined. The required page length of at least one print image to be applied onto the back side of the recording medium is adapted to the determined page length. At least one print line of the print image for the back side is printed repeatedly if the required page length for application of the rear print page onto the back side of the recording medium is smaller than the determined page length.
Claims16
A method for controlling an inkjet printing device having two printing units for printing to the front side and back side of a recording medium, the method comprising:
- determining a physical page length of at least one print image applied onto the front side of the recording medium;
- adapting a required page length of at least one print image to be applied onto the back side of the recording medium to the determined page length;
- and
- repeatedly printing at least one print line of the print image for the back side in response to the required page length for application of the rear print page on the back side of the recording medium being smaller than the determined physical page length,
- wherein at least one first print image and at least one second print image are to be applied on the back side of the recording medium, the second print image being arranged on the recording medium after the first print image, and the at least one print line to be repeated is inserted in proximity to a page end of the first print image and/or in proximity to a page beginning of the second print image, and
- wherein a first number of last print lines of the first print image and a second number of first print lines of the second print image are printed repeatedly in an arising intervening space between the first print image and the second print image for the back side.

An inkjet printing device, comprising:
- a first printer configured to print at least one front print image onto a front side of a recording medium;
- a second printer configured to print at least one rear print image onto a back side of the recording medium;
- a sensor configured to detect a marking located on the recording medium, and/or to detect an edge of an individual sheet;
- and
- a controller connected with the sensor and configured to:
- determine a page length of a print image applied at least onto the front side of the recording medium;
- and
- adapt a required page length of at least one print image to be applied onto the back side of the recording medium to the determined page length, wherein at least one print line of the print image for the back side is repeatedly printed in response to the required page length being smaller than the determined page length,
- wherein at least one first print image and at least one second print image are to be applied on the back side of the recording medium, the second print image being arranged on the recording medium after the first print image, and the at least one print line to be repeated is inserted in proximity to a page end of the first print image and/or in proximity to a page beginning of the second print image, and
- wherein a first number of last print lines of the first print image and a second number of first print lines of the second print image are printed repeatedly in an arising intervening space between the first print image and the second print image for the back side.
