Thank you!
CUPS is mostly working, I guess most of the basic functionality should
compile and run cleanly. Besides the sources already pointed out in this
thread, there's a patch at HaikuPorts[1] and there's the GPL source
code[2] from ZETA (a previously commercial BeOS distribution).
However, CUPS basically only implements general printer driver
management, not the actual printer support. A lot of the functionality
in CUPS is already supported by our current print_server & transport add
ons. The interesting parts (taking a closer look at the ZETA
implementation) is in foomatic[3], which is a database of printer
descriptions (it uses an XML database converted to PPD[4] files) for
describing the supported printers and their features.
The real interesting part, and what ZETA used CUPS/foomatic for, is the
actual printer drivers. Most of them use Ghostscript[5] backends to
convert Postscript to the output format used by the printer.
