I have set the /usr/bin/foo2hp2600-wrapper script to "-x" in the shebang
line to see what commands are run:

Sorry for the german output. Not sure how I can set it to english for
debugging. Anyway it appears like Ghostscript (gs) is called (although I
wonder why the "letter" format is chosen - I'm using A4 everywhere in my
settings). And gs pipes to foo2hp. And somehow during this piping something
unexpected is happening.

Strangely I can print *some* documents. I have created a new inkscape
drawing  and put the Debian logo and a few colored circles into it. That
printed well. However my hardly more complicated image (I wanted to print a
sign for our office door with our company logo and a little text on it)
didn't print.

Any ideas? Thanks!

 Christoph
