If anyone else want to tackle this go for it!
Anyhow, I've decided to grapple something a bit easier, something I
can work on in small chucks. That thing is support for CUPS.
I'm making a GSCUPS framework. Later will come a GSCUPSGui
framework, and finally some apps for managing CUPS will come forth.
Sure! What about adding CUPS support to NSPrinter as well? Or some
way for NSPrinter to use your framework.
I have been thinking about a CUPS printing backend for GNUstep GUI
myself some time ago. The results of my tinkering are attached. The
basic idea was to split off just the finding of the PPD file and the
transfer of the file to the printer. (As a side effect this would allow
us to remove the full set of PPD files currently delivered with GNUstep.
Perhaps we should put them in a separate ressources package anyway?)
As I never did find the time to really work on this, it is more a
starting point for further brainstorming than a real implementation.
