printing revisited.

Looking for input on what others are doing regarding printing, specifically with regards to *nix. Particularly interested in solutions that are *free* and also cross-platform. I understand most are probably using some sort of pdf creation method then piping the file out to the printer port. Anyone have any other creative methods for generating printable output? Anyone using the php postscript library? Perhaps creating a PNG or similar using imagemagick then piping that to lpt? I already wrote a bunch of code to perform printing using the php_printer library after somehow missing the WIN32 only disclaimer and now I have no solution for linux. If I have to write more printing code I think I'd rather replace the win32 only php_printer code with something crossplatform as it will be easier to maintain that way. Anyway, I'm aware of some of the alternatives but was curious if anyone had come up with an "outside the box" creative method of handling print tasks inside php-gtk. I'm still using version 1 btw but would be interested in hearing if/how php-gtk2 might simplify this task. TIA!
