Network Printing - IPP

Question

Network Printing - IPP

Forum newbie here...

I'm trying to set up my laptop to print to a network printer at work, using IPP, and it's not working. With the help of the sys admin i've identified the problem, but no-one here knows how to fix it.

For some reason my laptop is prefixing the print queue name with "ipp/", so that "printer/queue" is sent to the printer as "ipp/printer/queue". All i need to do is stop it from adding the incorrect prefix, but i've no idea how to do it (or, indeed, why it's doing it at all). There are about 50 people here with various different Apple laptops, and none of them have ever come across this before.

Any help would be greatly appreciated.

Powerbook G4, Mac OS X (10.3.9)

That may be caused by your turning on Printer Sharing on your Mac. It is only activated when you have a locally-attached printer and you want to share it with others, not when you want to use a shared network printer or server print que. I doubt you have a printer to share with others, so turn it off.

Printer sharing was already off (as i've never had a local printer attached to the laptop), so that's not it i'm afraid.

I have found a work-around - logging in as root and manually changing the address(es) in the printers.conf file, then restarting the CUPS daemon. It's a pretty ugly fix though, so a more elegant solution would still be appreciated.

Is it maybe that you should be using IP > LPD instead?
The two normal forms of the URI for IPP are this:
ipp://192.168.1.5:631/printers/queue_name
or
ipp://192.168.1.5:631/ipp/queue_name

IPP is not the same as IP printing, it is a newer IP printing protocol that came out around 1999-2000. LPD URIs have the form:
lpd://192.168.1.5/queue_name

What model printer is it? Do you need IPP or just old reliable LPD?

I tried it with LPR/LPD, but it gave the same problem. The printer is a HP of some variety, but it's set up as a "generic postscript" network printer serving a mostly-UNIX network. IPP is the preferred protocol, and many other (mostly Tiger) Mac laptops here don't have the same problem i do.

I've used the same setup many times in different places before with no problems, but i think the problem here is that the printer queue has a directory, rather than just a queue name (i.e., the queue name is "folder/printer1", rather than just "printer1"). As i said, it's fixed now and i can actually print, but the fix was sufficiently ugly that i wouldn't mind finding something better.

Try choosing it as a Rendezvous/Bonjour printer rather than IPP. It should be found in about a quarter minute or less, and I have found specifying Rendezvous/Bonjour seems to make the connection much more trouble-free.
