Ubuntu 10.04 printing fix: getting rid of the light yellow/cream background when there should be a white background

Update 4 June 2010: the latest round of updates took care of the problem. If you’ve not yet updated, try System -> Administration -> Update Manager. Thanks for the heads-up, Reinout van Rees!

Ever since installing 10.04, I’ve found that I occasionally get rogue light yellow/cream-coloured backgrounds when I print images with a white background. This hasn’t happened with my machines running 8.04 or 9.04.

I’ve had this problem printing from OpenOffice and from Firefox; in both cases, I was printing a .jpg with a white background. I verified with xmag that there was no colour in the background that I was trying to print.

There is a Debian bug report and an Ubuntu launchpad bug report with more information and a temporary work around.

Open a terminal window (Applications -> Accessories -> Terminal) and enter the following:

cd /usr/lib/cups/filter/

to move to the /usr/lib/cups/filter directory.

Optional: make a back-up of the file that needs to be edited by typing

and entering your log-in password if prompted.

Open the file pstopdf in your favourite text editor. This can be done using gedit by typing

sudo gedit pstopdf

and entering your log-in password if prompted.

There should be a line that looks like this:

PS2PDF_OPTIONS=”$PS2PS_OPTIONS -dColorImageFilter=/FlateEncode \
-dPDFSETTINGS=/printer -dUseCIEColor”

Delete -dUseCIEColor so that the line appears like this:

PS2PDF_OPTIONS=”$PS2PS_OPTIONS -dColorImageFilter=/FlateEncode \
-dPDFSETTINGS=/printer”

Save the file.

This worked for me with a Lexmark C544 printer. However, I don’t know what is causing the problem and I don’t know anything about what these options do. Fingers crossed, a ‘proper’ solution will be on its way….

Thank you, vbi, for the work-around!
