Hi Guys.. I'm having problems printing a PostScript docuemnt, very weird.

From the CLI if I do 'lpr file.txt' it prints OK.. when i do 'lpr file.ps' I don't get anything coming out of the printer.. any idea what's up? It only happens with PostScript docs…

Probably your printcap has a filter set up for postscript, but whatever it calls to interpret postscript is not installed.

Unless it's a PS printer, of course. bu in that case "lpr textfile" wouldn't work without manual setup to convert TEXT to postscript.
it is a postscript printer

I'm printing to it with a PPD driver
check your printcap, make sure it's not doing something stupid.
a ppd isn't a driver, really, just a description of printer capabilities.

I see
Durtro, my printing skills really suck.. How do I check my printcap?
the printing howto will tell you about that, and the printcap manpage.
thanks Durtro
