Drivers exist for a number of newer printers that are not included with Red Hat 6.0 (or earlier). I spent an afternoon figuring out how to recompile ghostscript including the hpdj and cdj850 modules. I'm willing to work with someone inside Red Hat to get these included in Red Hat updates, since it will be a long time before either is officially supported by ghostscript. (cdj850 is apparently included in ghostscript after the 5.50 release.) I didn't use RPM to compile these modules but am willing to learn how to modify a spec file to do so. I thought I would post here before I did so.
Because of the ghostscript license, we can only ship the previous release of ghostscript, so newer printers are often not included. If you have a contributed driver that we can include in ghostscript, then attach to this message. Otherwise, grab a newer ghostscript package or wait for a new release of ghostscript so that we can upgrade.
Right. Of the two ghostscript modules I use for my printer, one still isn't part of ghostscript as of 5.50 and the other will be for whatever version is released after 5.50. The two contributed drivers I was hoping Red Hat could include in future ghostscript releases can be found at: hpdj version 2.5 ftp://ftp.pdb.sni.de/pub/utilities/misc/hpdj.html hp850c version 1.3 (The beta test 1.4 version will not compile with ghostscript 5.10 without changes because it is intended for gs5.50 and beyond.) http://www.erdw.ethz.ch/~bonk/hp850/hp850.html Let me know if you need any more information than this and if there is anything else I can do to help.
The hp8xxs13 driver from www.erdw.ethz.ch is in as of 5.10-8
5.10-9 includes hpdj driver and should be in the next rawhide release.
