Greetings All,

I'd like the iMac in the next room to be able to share the Canoni850
attached to the USB port of the Quicksilver on my desk. Printer sharing
is "on" in both machines, both machines are running 10.2.3, both have the
Canon software installed, both have been rebooted several times.

The iMac will not print to the shared printer. It has now accumulated 10
print jobs in the queue. I can't select and delete the printer. I can't
select and delete the print jobs. Each job dialog reports: "Unable to
connect to IPP host: undefined error: 0".

A careful check of the Apple kbase has nothing. A google on the error
message finds nothing directly relevant but brings me a lot of CUPS and
IPP related info that makes me hope that I don't have to learn it all to
solve this!

Thanks!

does the imac autodetect the printer when both machines are on, or did you manually set it up?

The iMac found the printer originally but no longer does. Odd because other computers running 10.2.3 can find and print to this shared printer...

My wife has a flat-panel iMac with an HP DeskJet 970Cxi printer attached to it over USB. She's got an AirPort card in the iMac; I (used to) have a dual-USB iBook with an AirPort card; and we're attached over a graphite AirPort Base Station that's connected to DSL via Ethernet. The DSL provides us with 5 static IP addresses.

At one time, after Jaguar was released, I was able to print from my iBook to the DeskJet attached to my wife's iMac. I'm not sure what changed, but at some point I started getting the same error as you did.

I looked around at everything trying to fix it. Eventually, I figured out that CUPS seems to be looking for the hostname "imac" rather than "imac.local" which it should be for Rendezvous-discovered hosts. So I added "imac" to my /etc/hosts file and the problem went away and hasn't appeared since.

However, I just upgraded from my iBook to a 12" PowerBook with AirPort Extreme. One of the first things I did was try to print to the auto-discovered DeskJet. It gives me the same IPP error message. So whatever it is, it's something on the iMac side.

Also, on the iMac, I've tried several times to reinstall HP device drivers; I think I even tried installing an older version, I'm not sure.

I'm out of ideas, other than the /etc/hosts hack, and I haven't found anybody else with the same problem.
