For now, used the CUPS driver.<BR /><BR />SEP Fri, 16 Jul 2010 12:22:31 GMT Steven E. Protter 2010-07-16T12:22:31Z https://community.hpe.com/t5/operating-system-linux/hplip-and-cups/m-p/4662325#M80975 I have installed RH 5.5 to be used as a CUPS server, and upgraded cups to the latest version. To get the latest HP drivers, I then installed the latest hplip from hp's site. Any driver I attempt to used from this set just stops any job entering the CUPS queue, and will not release it. Once I change to any other driver supplied by the CUPS software, the job then is released and prints. Any thoughts?<BR /><BR />RickB<BR /> Fri, 16 Jul 2010 11:52:46 GMT https://community.hpe.com/t5/operating-system-linux/hplip-and-cups/m-p/4662325#M80975 RbaileyNC 2010-07-16T11:52:46Z https://community.hpe.com/t5/operating-system-linux/hplip-and-cups/m-p/4662326#M80976 Shalom Rick,<BR /><BR />If this hplip is from the Proliant Service Pack, that package probably does not support RHEL 5.5<BR /><BR />You will have to live without PSP until it is released by HP.
