Red Hat Bugzilla – Bug 251211
CUPS version 1.2.12-2.fc7 will not give you the option to print to a parallel printer.
Last modified: 2007-11-30 17:12:12 EST
Description of problem: Latest CUPS version breaks parallel printing. No
printing is possible through a printer on a parallel port.
Version-Release number of selected component (if applicable):
How reproducible: always
Steps to Reproduce: Using either system-config-printer or http://localhost:631
to access the CUPS interface directly, I cannot get anything to print to my HP
Laserjet 4000N. This is because the new version, for whatever reason, doesn't
accept parallel printers. This problem has just shown up in the latest version.
Installed with an "yum -y update". I do not know what the previous version of
Actual results: Files go into the printer queue; printer appears to be dead and
it does nothing.
Expected results: Printer should start printing.
Using http://localhost:631, I also get the following error message on screen
after attempting to start the printer:
Also, when the error message comes up, the printer state is:
Make and Model: HP LaserJet Series Postscript (recommended)
State: stopped, accepting jobs, published.
Device URI: parallel:/dev/lp0
We now the problem, per the fedora-users list, and I can't believe I didn't
see it. There's no parallel printer option! The previous CUPS version worked
and rolling back to it fixes the problem. Can this be done, please?
Yesterday printing worked, today it did not. Looking at my yum.log (tail of it
below), udev was the only possible culprit. The last update was a few days
ago, and I had no problems then.

Reverting to an older version of udev solved this problem for me.
udev-106-4.1.fc7.i386.rpm (my older cached RPM file)
udev-113-8.fc7.i386.rpm (my latest update, from yesterday)
rpm -Uvh --oldpackage udev-106-4.1.fc7.i386.rpm
That, plus a reboot, was the only thing I did to get parallel port printing
working again, for me. The reboot probably wasn't necessary, but I couldn't
remember how to restart udev. The downgrade, alone, wasn't enough.
Now, I can also add a new parallel port printer, via the CUPS HTTP interface.
Today, before I diddled with udev, the LPT option wasn't on this list.
I think this bugzilla needs redirecting towards the udev package.
