Re: [K12OSN] Ongoing printing problems k12ltsp V8



What version of CUPS are you using? I had a similar issue with the CUPS backend failing to interprit something and it took the printer offline.  I used some script someone wrote to monitor it and when id went ofline it put it back online.  That was with CUPS 1.1.  I have not had the issue since I updated CUPS.  I would recommend installing the newest version if you haven't already.  it is really easy..
see this... http://www.cups.org/software.php#RPM 
          rpmbuild -ta cups-version-source.tar.gz
   or:
          rpmbuild -ta cups-version-source.tar.bz2

Also make sure this is up todate too or that you have it installed... http://hplip.sourceforge.net/index.html
Their drivers are sweet. :)
Hope that assists you in getting it to work properly.  
Oh yeah... occationaly cups disables my networked 3005 laser printer.  Don't know why but it is very rare.

Norbert,
	the change is in the cups. If you can downgrade to an older
version, the problem should go away. Cups has a difficulty with chatty
printers, and hp printers are downright garrulous. The jetdirects ex are
less talkative. you can see that if on the printer you enable logging to
your server syslog. Btw, I see no problems printing with 5EL.
