Re: Developement of a new postcript converter.
Note: You Cc'ed Macro Pistore, probably because he is mentioned as the
maintainer in the gs-packages you use. Marco gave away maintenance of
Ghostscript - I am the current maintainer of those packages.

GNU did not write Ghostscript. Better write to Aladdin for such questions.

What lacking here is the support from the printer manufacturers. Having the
specs for the printer you can assume that a driver will be available soon.
I would write such a driver if provided with the printer and its spec.

Why reinvent the wheel? Ghostscript is there and it is free software. It is
our strength to use what is available and extend it as we see fit. No need
to write a new program.

Well then, implement a dynamic loading facility for Ghostscript.

Great. This means we are still unable to use all the features the printer
provides if the manufacturer decides not to implement it in the driver.

Please write to HP asking for the specs. Surely someone would want to write
the code. I would do it if I had such a printer.

Well, I would suggest to look around on the free software market for similar
projects. Then contact the people who fit in here. Currently I know of the
following projects regarding printing:
- CUPS: Common Unix Printer System (www.cups.org, has a modified ghostscript)
- APS: Application Printing Services API (see opensource.corel.com)
- gnome-print(?): GNOME is also working on a print architecture. I bet KDE
is doing something as well. Look at the respective homepages (www.gnome.org,
Further projects might be found using http://freshmeat.net/appindex, linux.com
I am the Debian maintainer of Ghostscript and I plan to do something in that
direction for the Debian package. I think the drivers should be loaded as
dynamic objects at runtime and the compilation should support just plugging
in a Driver and only compiling that module.
I would like to elaborate but I don't have the time before Feb 15th. Sorry.
Please keep me informed on your results.
