Answer:
A difference between the printout report and the paper printout can be caused by the cover sheet, as this is not numbered.
If this is not the case, the following cause is possible: A printout report is always created by the printer driver defined as the default. Therefore, you should also use this default printer. To find a solution, set the "paper printer" as the default printer, or install a new printer driver and set it as default.
Driver updates can be found, for example, at www.treiber.de.
