I am a member of the Silicon Valley Linux User Group (SVLUG) and I noticed that several of us when installing Redhat 6.1 end up with no lp0, lp1, lp2 detected, as well as no printer daemon present errors. In short, our printers that worked fine with Redhat 5.2 and 6.0 are not found in Redhat 6.1 Upon entering cat/proc/devices, under Character devices, number 6 lp was missing on my PC which would help explain about the printers not being detected. We also noticed that there was no printer setup in Redhat 6.1 like there was in Redhat 6.0 and 5.2 installations. Printing capability is important. Please help.
You've got two problems here. The first looks like a duplicate of #7341, which is a bug in the installer. Per Bero's comments there, add the line: alias parport_lowlevel parport_pc to your /etc/conf.modules file and see if that helps. As for the second, please verify that you have the printtool package installed. It can be fetched from this URL: ftp://ftp.redhat.com/pub/redhat/redhat-6.1/i386/RedHat/RPMS/printtool-3.41-2.noarch.rpm Please let us know if this solves your problem.
I'm also told that this problem is fixed in the latest modutils release in Raw Hide.
