In the never-ending quest to tweak things so that they work just a little bit better I've managed to enhance Ghostscript so much that I can't print anymore. :-(
Here's the deal. Running RH 7.2, had things working fine but saw that the hpijs driver promised better print quality and options. So I changed from using the cdj550 driver to hpijs. Hmm, not much difference. Ho hum. But it still worked okay. So I notice that there is a new version of hpijs that promises whizzy new features, blah blah blah. But to use it I need a newer version of Ghostscript (6.53) because the version I have (6.51) doesn't have the enhancements needed to support the new hpijs. Okay, upgrade Ghostscript then. But there's no RPM. Not a problem, get the tarball and build it. Piece of cake. Got it all installed, ghostscript works great, ghostview works great, printing doesn't work at all. It is amazing how hard it is to find out where logging of printer problems actually happens! It is not in the system log (/var/log/messages) like you might expect. Nah, that would be too easy. You have to look in /var/spool/lpd/<queue-name>/lpq.0 in order to see what is really going on. Sigh. So now I've nailed it down but don't like the obvious solution of going back to the previous version of Ghostscript. The problem is that the new version of Ghostscript includes a driver for the newer ijs and not hpijs. The ijs driver incorporates all the older hpijs functionality with an abstraction layer that allows to work with non-HP printers as well. The magic filter on the printer queue calls Ghostscript to process the input stream with a driver specified as hpijs. I'm trying to find where the configuration info that governs the structure of the command line passed to Ghostscript can be found. My thinking is to change the way that Ghostscript gets invoked by the printer's magic filter. So, does anyone out there know how to do this? -- Dan Coutu Managing Director Snowy Owl Internet Consulting, LLC Mobile: 603-759-3885 Fax: 603-673-6676 ***************************************************************** To unsubscribe from this list, send mail to [EMAIL PROTECTED] with the text 'unsubscribe gnhlug' in the message body. *****************************************************************
