I'd like to make a "printer" on my fedora box that actually just generates a series of .png files for each page in a print image directory. I've found all the info I need to pass to ghostscript to get it to do this (it has a handy png output driver built in), but brain matter starts leaking out my ears when I try to understand how to invent a .ppd file and integrate this with cups so I can spool things to this "printer". Anyone out there ever done such a thing and have some cofig files I could steal?
