• Product: Gentoo Linux
• Status: RESOLVED NEEDINFO

[Description Pun 2010-05-05 19:11:52 UTC]

WhenI try to print via cups-pdf any document that uses font AvantGarde-BookI get an empty pdf. When I tried yo investigate the problem by choosing "Print to file" in printing dialog I got a perfectly valid postcript document that was correctly rendered by ghostscript. When I tried to convert that very ps file with ps2pdf I got the following error:
 gs -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -dSAFER '-sstdout=%stderr' -sOutputFile=pf.pdf -c .setpdfwrite -f pf.ps

However, ps2pdf and scripts it calls being shell scripts, I was able to reconstruct the command actually passed to ghostscript, namely:
gs -dNOPAUSE -dSAFER -dBATCH -sDEVICE=pdfwrite '-sstdout=%stderr' -sOutputFile=pf.pdf -c .setpdfwrite -f pf.ps
I tried to remove the option -dSAFER leaving the rest options intact and I got my pdf rendered. So, IMHO either ghostscript should be instructed to trust  the standard font path out of the box or the option -dSAFER should be removed from ps2pdf and friends, especially if you would like to get rid of users with mysterious cups-pdf problems ;-).


Reproducible: Always

Setting 
/etc/env.d/99ghostscript:
GS_LIB=/usr/share/fonts/urw-fonts
has solved the issue for me. Can you please add setting this variable to the ebuild?

The standard font path is /usr/share/fonts/default/ghostscript which should be a symlink to /usr/share/fonts/urw-fonts in all recent ghostscript-gpl versions depending on urw-fonts. Please verify that the symlink exists on your system, attach an example ps, emerge --info output, which cups & cups-pdf versions you're using, out of which programm you're trying to print and anything else which helps reproducing your issue.
