Rick,
The following assumes that your printer is an HP LaserJet 4100N/DN/DTN
model. The important part of the model number is an "N" in the suffix which
would indicate it has a JetDirect Ethernet port.
JetDirect (port 9100) network print servers are admin-friendly in that they
do not have to be managed by a Windows or UNIX server queue like dumb
parallel- or serial-port printers. Any system on your network can be set up
to print to it as though it were directly attached.
1. Select Desktop -> Preferences -> Printer (printconf-gui) from toolbar
<This is the FC4 path. RHEL4's path differs, but you already know that.> 2.
Click on New icon 3. Click on [Forward] button 4. Enter queue name &
description] 5. Click on [Forward] button 6. Select the "Networked
JetDirect" queue type 7. Enter the printer's network name or IP address 8.
Click on [Forward] button 9. Select "HP" then "LaserJet 4100" as the make &
model 10.Click on [Forward] 11.Click on [Finish] 12.When asked, click on
[Yes] to print a test page. After long pause to save the new configuration,
a test page should appear.
Note that neither JetDirect servers nor Internet Printing Protocol queues
(which CUPS implements) use ports that are commonly set up to pass through
firewalls. This includes conventional enclave boundary protection firewalls
(hardware), and individual server & workstation firewalls (software). Make
sure all firewalls between you and the printer are set to pass port
TCP/9100.
Hope this helps...

Hello Doc,
Yes, it is a 4100N (had to drive down to the office to check on that). Just
a few minutes ago, I took some steps suggested by Tom Sightler.
Reinstalling everything did not seem to help.
Prior to replying to your advice, I re-did the install. This time I made
the queue available to other computers (check box in the sharing properties
of the printer). It seems to have succeeded, but I have to wait until
tomorrow to see if it actually printed. I'll report back. Thanks for your
help.
Regards,
Rick Danielson
