The problem in Precise (12.04) 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.
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. Please test the package as soon as it gets available for
download and give feedback here. This is required to make the new
package an official update for Precise. Another comment with testing
instructions will get posted here.
With the new package you can also test the behavior when switching
between use of Poppler and Ghostscript and changing the resolution
limit. Run the following commands in a terminal window for switching
between Ghostscript and Poppler:
lpadmin -p <printer> -o pdftops-renderer-default=gs
lpadmin -p <printer> -o pdftops-renderer-default=pdftops
and
lpadmin -p printer -R pdftops-renderer-default
to remove the setting. To change the resolution limit run a command like
lpadmin -p <printer> -o pdftops-max-image-resolution-default=1440
and set unlimited resolution via
lpadmin -p <printer> -o pdftops-max-image-resolution-default=0
or remove your setting with
lpadmin -p <printer> -R pdftops-max-image-resolution-default
Always replace "<printer>" by your printer's queue name (enter "lpstat
-v" to find your printer's queue name).
