Comment 5 for bug 237759

Hi,

I'm looking into a similar problem, but I am getting it with completely different Hardware..

I've got a samsung ML-1510 laser Printer and An Epson R800 Inkjet connected to a 3205uw print server. The connection is over wired ethernet and a Windows PC also uses these printers. The windows PC works faultlessly.

I have configured the Printers through cups (http://localhost:631). Both printers have the correct drivers and are being addressed correctly via IPP. I can get an initial test print off each and then that's it. The cups screen shows no active jobs but the status of both printers as "waiting for active job to complete". In Gutsy cancelling the job cleared this. It does not appear to do so in Hardy.

I've used Firestarter to allow incoming traffic from the Edimax Printserver, so I don't think it's a firewall problem.

Digging a bit deeper I had a look at /var/log/cups/error_log and found:
Code:

E [09/Jun/2008:08:20:02 +0100] CUPS-Add-Modify-Printer: Unauthorized

It looks like some sort of permissions problem but I can't figure out what as yet. I suspect it's in CUPS, but I'm not clear what. I've tried setting the CUPS Server to allow any user to cancel jobs, but that has not worked

That's where I'm at - I've attached the printbuginfo output file. The only thing that strikes me is that there is no (apparent) driver for the Epson R800 even though i installed one from the CUPS configuration page and there are Konica Minolta and HP drivers I didn't install.
