Unable to collate using internet print protocol

We have a 200 user network with several networked printers. All of the
networked printers are set up to use internet print protocol. We have
discovered that none of the printers will collate print jobs that have been
sent to them using IPP. Even if the print job is set to collate at the local
machine, the job will output uncollated on the printer.

The IPP client that we are using is a novell client, however, according to
Novell, the issue is also present when using Microsoft's IPP client. Also
according to Novell, there is supposed to be a hotfix from Microsoft for this
issue. I haven't been able to locat this on the knowledge base, and a phone
call to Micrsoft tech support also yielded no solution.

I'm wondering if anyone else has seen this issue and has found a fix for it.

Thanks!
