Can't print to CUPS from WinXP

[Jens Cedlind]

Hi,

I've set up CUPS on one machine (running Edgy), and I can print from 
both the machine the printer (an old HP LaserJet 4L) is connected to, 
and from other Edgy machines on my home network.

The problem comes when trying to print from WinXP machines, using both 
the default driver Windows installs and the PostScript driver found on 
HP website.

It's set up to allow connections from 127.0.0.1, 10.0.0.*.

access_log shows:
10.0.0.4 - - [17/Nov/2006:17:08:37 +0100] "POST /printers/LaserJet-4L 
HTTP/1.0" 200 35795 Print-Job client-error-not-possible

for each tried printjob and multiple

10.0.0.4 - - [17/Nov/2006:17:09:04 +0100] "POST /printers/LaserJet-4L 
HTTP/1.1" 200 185 Get-Jobs successful-ok

 From this, it seems to me that the client can connect and get queue 
info ok, but when it tries to print, CUPS doesn't understand the data 
sent. (Wild guess on my part)

I've googled high and low for a few hours now, and only relevant info, 
was that this might happen if there was no quota set.
I tried setting quota to 100 pages during 1 hours, no sizelimit.

cups error_log shows nothing.

I've tried using both http:// and ipp:// as printer URIs, both without 
any luck.

The admin pages and printer info etc can be access fine from the WinXP 
machines.

It should be mentioned that I'm *not* running Samba on the computer, 
although most guides out there tells you to set up both. I really don't 
find it relevant when using the IPP/HTTP protocols for printing.
Please correct me if I'm just stubborn and wrong :p

ty in advance,
Jens Cedlind

PS: sorry if it's a tad out of bounds for this list.
