Hi,

I did not know that Tim was the printing man, but I did run the "printing 
troubleshooter" (which for me is the Troubleshoot button on 
system-config-printer, is that the right thing?) Sorry to be naive, but how 
does one enable the system to discover network servers?

Thanks very much, everybody, for all the help and advice.

one of the problems with an active list is that you don't always know
whose advice to follow and who is just taking shots in the dark.

When it comes to printing ALWAYS follow Tim Waugh's advice because he is
Red Hat/Fedora printing man. As far as I can tell, you ignored his
advice and chased down everyone else's.

You probably haven't enabled your system to discover network servers but
I think Tim suggested that you run the 'printing troubleshooter'

Yes, I poked holes to allow the samba and ipp clients through, as well as the 
ipp server. Trouble is, I do not understand what to look for. How do I trouble 
shoot when the messages in /var/log/messages do not appear to be beyond the 
information I provided. Is there any other place to look at?

The ubuntu machine seems to do just fine in discovering the network printers: I 
am just trying to understand what is going on here.

I had mis-remembered.  What it actually said (page 10, if you have LXF 124, 
November) was that the firewall by default turns of multicasting.  The 
'comment' is a bit of a rant, saying that if something as vital as this is 
disabled there should be some way of alerting you to it.

That rules out SELinux, then.  If you haven't done so, check firewalls - but I 
think someone already told you to do that.

Thanks, Anne. Where is this article? Btw, I went and disabled selinux using 
system-config-selinux but the printers were still not discovered. I have 
reverted it back to enforcing, but I wonder what the problem is, and how to 
troubleshoot it.

Hi,

Thanks so much! I went back and enabled both the Samba and Samba Client options 
on my firewall. Do I need both? Even then, no luck. 

I am not sure what these other systems you refer to are. They may either be 
Windoze XP (most likely) or RHEL (4 or 5). How can I find out?

Best wishes,
T

I didn't have to fiddle with SELinux to get my Fedora 11 installation to
find the printers on my LAN (one served from an old Fedora Core 4
installation, and another from a Fedora 7).  All I had to do was make
sure that Fedora 11's firewall allowed the CUPS client.

I didn't look for a printer using system-config-printer, though.  I
visited , and waited for it to show up.
There's some delay, but I don't recall that the scan period is very
long.  Restarting a CUPS client or server usually produces quicker
results for the impatient.

There's an option to "show printers shared by other systems" that's
ticked on the  page (which means to *show*
printers elsewhere on your LAN, as opposed to just the ones directly
connected to the computer you're working on), but I think that was
already ticked by default.

If your remote printer that you're unable to find is on a different
sub-net (e.g. 192.168.1.x versus 192.168.2.x), you may need play with
more settings on the server.

Right or wrong, the statement was that the default SELinux blocked network 
printers.  I haven't got it in front of me, but it went on to say what needed 
allowing in SELinux to make it work.

Don't shoot the messenger ;-)

Is 'Show printers shared by other systems' enabled in the server

If it is, and your firewall is set to enable UDP packets in on port 631
("IPP client"), the printing troubleshooter might be able to tell you
waht's wrong: Help->Troubleshoot.

According to Linux Format this month, if you have SELinux running this is to 
be expected, so you'll have to look for a way to allow the broadcast through.

Are the printers truly network printers or are they printers attached to 
other systems (and what are these systems if they exist)?


If the other printers are on Windows, have you tried enabling samba
