had 6.0... installed redhat 6.1 on a workstation.... went to print.. no go.. no error log.. nothing.. same setup as before. checked config on 6.0 server... no problems... installed newest lpr on both machines (now rh 6.1 lpr on both) -- still no go.. no error messages or anything... installed 6.0's lpr on both machines and it all started working.
Bug 5752 has been closed because Red Hat Linux 6.1 is no longer supported by Red Hat, Inc. I could not duplicate with Red Hat Linux 7.3/8.0 so consider this a bug that is fixed in current release.
