To change the resolution limit run a command like Lpadmin -p printer -R pdftops- renderer- default Lpadmin -p -o pdftops- renderer- default= pdftops Lpadmin -p -o pdftops- renderer- default= gs Run the following commands in a terminal window for switching between Ghostscript and Poppler: With the new package you can also test the behavior when switching between use of Poppler and Ghostscript and changing the resolution limit. Another comment with testing instructions will get posted here. This is required to make the new package an official update for Precise. Please test the package as soon as it gets available for download and give feedback here. I have uploaded a cups-filters package to precise-proposed now which switches back to Poppler and limits the image rendering resolution to 360 dpi. The problem is most probably caused by switching the pdftops CUPS filter from Poppler to Ghostscript and allowing higher image rendering resolutions when the pdftops filter has to turn graphical structures of the PDF input file into bitmaps when converting to PostScript and PostScript does not support these structures.
