Dell 3010CN + cups

[Flavien]

Hello,


I just got my hands on a Dell 3010CN laser color printer. I'm 
trying to get it working with our cups printing server (Linux 
Debian).

I read in the archives that it's supposed to work :
http://lists.us.dell.com/pipermail/linux-precision/2006-November/001051.html

Corresponding section of my cups/printers.conf file is :

    <Printer dell-3010cn>
    Info A4 Laser
    Location Office
    DeviceURI socket://dell1:9100
    State Stopped
    StateMessage Print file sent, waiting for printer to finish...
    StateTime 1173352662
    Accepting Yes
    Shared Yes
    JobSheets none none
    QuotaPeriod 0
    PageLimit 0
    KLimit 0
    OpPolicy default
    ErrorPolicy stop-printer
    </Printer>

I can see that cups tries to send the job to the printer : tcpdump
shows that there's a connection from my server to the IP of the
printer. The printer does not print anything however, neither shows 
any error message on the screen or any sign of activity. A few 
details :
* I checked the IP filters on http://XXX/ews/setting/setipfilt.htm
* I rebooted the printer
* If the IP filters do not include the IP of my server, I get the
  same result (?).
* The "conversation" I see in tcpdump is just my server sending the
  postscript file directly on port 9100 on the printer and no answer
  from the printer (normal ?).
* The job stays in cups queue.

Any hints ?

Thanks.

Flavien.
