Do you have Mac OS X 10.6.7?

Not yet. And for obvious reasons I'm not willing to update right now ;)

The small attached example is enough to break the printer (both PostScript and PCL) when printing from Skim. May I ask you to try to print this file with 10.6.7?

No problem here. BTW: pdfinfo a.pdf Title: a Creator: ConTeXt - 2011.03.11 11:45 Producer: LuaTeX-0.65.0 Page size: 595.276 x 841.89 pts (A4) File size: 5253 bytes PDF version: 1.6 pdffonts a.pdf name type emb sub uni object ID ------------------------------------ ----------------- --- --- --- --------- ZWRPON+TeXGyrePagella-Regular CID Type 0C yes yes yes 18 0 That file was generated with MKIVtexgyrepagella-regular.otf using mkiv? Now if I print that via CUPS-PDF. pdfinfo cups-a.pdf Producer: Apple pstopdf Page size: 595 x 842 pts (A4) File size: 2891 bytes PDF version: 1.3 pdffonts cups-a.pdf name type emb sub uni object ID ------------------------------------ ----------------- --- --- --- --------- CFOFGB+TeXGyrePagella-Regular Type 1C yes yes no 4 0 du -b a.pdf cups-a.pdf 5253 a.pdf 2891 cups-a.pdf So CUPS does some font conversion here. I would assume that will also happen when printing to a regular network printer. Maybe this step breaks on your system. And that is why sending the file to the printer directly causes no trouble. Florian PS: Is there a way to force luatex writing fonts in CFF instead CID format?
