It is necessary to restart CUPS when a change is made to the PPD file: I then edited the PPD file and changed the x,y coordinates of the bottom left of the imageable area from 0,0 to 10,3 for A4 paper so the file now contains the following: user $ sudo grep "ImageableArea A4" /etc/cups/ppd/MP510.ppd I had a look at the values of the ImageableArea for A4 paper in the printer’s PPD file, and the as-installed values were as follows: user $ sudo grep "ImageableArea A4" /etc/cups/ppd/MP510.ppd The CUPS printer test page (A4 paper) shown below is from a Canon PIXMA MP510 printer using the Gutenprint v5.3.3 driver for that model. This happens when I use the Gutenprint printer drivers, although I do not know if that is a coincidence.

Also, the left side of the test page image is too close to the left side of the sheet of paper. When I set up a printer using CUPS Administration and then print a test page, for some printers the bottom of the test page image is cut off, as shown in the scanned image below. This is something that has been bugging me for years but I never bothered to look into it until now.
