bash, I have seen that you have printed printertest.pdf with the Adobe Reader. The cutting which you have now comes most probably from the Adobe Reader. It reads the PPDs from the CUPS queues and uses the data to offer you paper size, input tray and duplex options (in the "Proprties" sub dialog of the printing dialog. It also uses the margin information from the PPD file for adjusting the printout size. This is controlled by the "Page Scaling" option in the "Page Handling" group. You have probably selected "Fit to Printable Area" or "Shrink to Printable Area", which makes Adobe Reader scaling or clipping the document into the printable area according to the PPD file. So the output of Adobe Reader does not put anything into the last 12.7 mm of the page. As you know that the borders in the PPD are wrong, choose "None" for "Page Scaling" and Adobe Reader will output the file in original size without clipping. Or edit the PPD file to get the best from the "Fit to Printable Area" and "Shrink to Printable Area" settings.
Aaron, here you see that it is very important that the PPD files represent the exact capabilities of the hardware. With the too conservative margins functions like "Fit to Printable Area" and "Shrink to Printable Area" (and also number-up or fitplot in CUPS) will not give the desired results.
