Errors printing PDFs with CUPS

This is another of those posts to not forget. If printing a PDF file with lp prints a blank page with error messages like:

ERROR: configurationerror OFFENDING COMMAND: setpagedevice STACK: –nostringval– …

the problem is probably that your PDF has a certain page size (let's say letter) but your printer expects another (let's say A4).

Check your printer settings and your PDf (with lpinfo pdffile) to verify. If this is the case, print with this command instead:

lp -o fit-to-page pdffile
