Lucky you :-)

Yup, that's what I figured, too.

Me neither.

That's what I figured, too. Apparently, many printers and print  
server running on Unix had trouble with Apple PostScript files that  
still contained some parts in the PICT format, so this filter gets  
rid of that. At least that's the impression I got after doing some  
googleing.

Tell me about it. Since your 10.4.4 does it right it rather seems to  
a problem with my setup. Or something. Oh, well....
