However, whatever value I used for the y coordinate of the bottom left of the test image, the bottom line was never printed. So I tried editing the y coordinate of the bottom left of the ImageableArea in the PPD file for the Canon PIXMA MP560. However, as with the original test page for the Canon PIXMA MP510, the bottom line of the test page was missing. Unlike the original test page for the Canon PIXMA MP510, the vertical lines on the left and right sides of the test image are more or less equidistant from the edges of the paper. The as-installed values of the ImageableArea for A4 paper in the printer’s PPD file were as follows: user $ sudo grep 'ImageableArea A4' /etc/cups/ppd/Canon_MP560_Wi-Fi.ppd A scan of the printed test page is shown below: I also have a Canon PIXMA MP560 printer, and I printed a CUPS ‘Printer test page’ on that using the Gutenprint v5.3.3 driver for the Canon PIXMA MP560. Now the ‘Printer test page’ printed by CUPS looks like this:ĪDDENDUM (): I have discovered that the ImageableArea is not the only factor… Lubuntu 20.10 installation using systemd user $ sudo systemctl restart cups Gentoo Linux installation using OpenRC user $ sudo rc-service cupsd restart 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.
