Intrigued by this thread, since I use networked printing
all the time, I tried
to use the cups interface on this box to add another
configuration of my
printer. It appeared to complete, telling me that it had
added the printer.
Checking on the server, I found that no new printer had
been added there.
Wondering if it had merely set up a local configuration
to be piped through,
I decided to try a test print of a photo. The new printer
didn't show up on
the printer list. Then I tried to print a test page, and
got the message
that the target printer doesn't exist.
Way back in 2000, when I worked at RH, I had to come in from the
cold and admit that I couldn't get my GF's printer to work at
all. Toxic SHAME!! I brought the entire system to work, and no
one else could get it to work, and they were the REAL experts!! I
finally rpm -e'd samba. God only knows why or how that came to me
to do so... and then the printer worked. I had beat myself up for
over a -year-, and had come to the conclusion that there was
something fundementaly wrong with me / linux / my system and it
was Samba, all along.

So, you might wish to check out your printer running locally
first, then jump into the networking end. Your message indicates
it works OK on localhost. That's good. Beat on your samba
settings, that's most likely where your permission problem lies.
I still shudder to think about the hell I went through with
emails and postings all over the place just to locally print a
page. <shudders> Ric

Great idea and I certainly would consider it if I was using samba.
However, none of my machines have ever had samba
enabled/configured. My network is pure Linux so the samba realm is
not needed.

And I've been using Samba for about 7 years, but never as a printer
server, none, nada. Cups and ipp have worked for all printer
sharing and nearly always have. No local configuration required
other than to look at localhost:631, wait for it to find all the
servers printers and quit. From that point on, anything I print
brings up a requester to check if I want to use the default printer,
I click ok, and a wee bit later I have inky paper on the output
tray. And we're being told that should be all thats required if the
printer is attached to a machine on the same subnet.

So my advice is not to get rid of samba, but to take any and all
references to the printers out of /etc/samba/smb.conf, on all
machines, then restart samba and see if that helps.

rather curious advice from someone who uses smbfs instead of nfs to
share files between Linux systems.

Chuckle, but be carefull how hard you throw those brickbats. Here, I
was never able to make NFS work until kernel 2.6.16, when it suddenly
seemed to be functional. I'd brought my error messages and NFS
failures to this list intermittently now for several years, and no one
was ever able to walk me thru to a working system till now. The errors
I was seeing simply didn't make sense to most and they, not knowing the
answer, simply ignored it after a while cause it worked for THEM while
I was out in the middle of the creek without a paddle.

So my file sharing here has always been either samba or rsync driven.
And since samba Just Works(TM) the perceived lack of speed hasn't been
a very large consideration based as much on the premise that I don't
fix what ain't broken. What perms samba can manage to fubar I can
always fix if they become a problem.

Samba automatically gets/shares cups printers with only minor
adjustments to smb.conf on the cups/samba server. I find using
Windows/Samba based shared printers easier to use than cups shared
printer but I can do either. Samba configuration on a system
attempting to use a remote Windows/Samba based printer is not
meaningful.

FWIW, it may not be workable on winderz either, and frankly I haven't
checked to see if winderz can see one of the cups/ipp printers on this
subnet. If I was going to actually run winderz (spit) then it might be
a consideration. But that will only happen if fc5 breaks itself & I'm
out of reach of the repair disks. Not likely since they are in the cd
case in the lappy's carry case already.
