Hello, fellow Slackware users!

I am trying to use CUPS 1.1.23 to print to my department's main
networked printer, a Xerox Document Center 470ST, from my Linux laptop.
My problem is that the IT department "naturally" doesn't support Linux
and won't even tell me how everything is configured...

The only information I have is:

- when I send a print job from my Windows machine, the printed pages
show up under a cover sheet which has my Windows/Novell username
written across it in big letters

- going to the Windows control panel of a computer which can print to
the Xerox, selecting this printer, "Properties" and then "Ports" shows
that it is "talking" to the printer over "Standard TCP/IP Protocol" to
the address 128.122.182.248 on port 9100. The selected protocol is
"raw" (rather than "LPR").

Does this mean that this is a Windows printer and I should be using
Samba? Or that it is using Novell? (If so, can I still use CUPS?) I
tried configuring CUPS to send jobs over either IPP or LPR to
socket://128.122.182.248:9100 using the recommended PPD for the
Document Center 400
(http://www.linuxprinting.org/show_pr...ent_Centre_400)
but always get an "server-error-internal-error" message.

The /var/log/cups/error_log file is filled with nothing but

E [24/Oct/2005:13:37:25 -0400] AddCert: Unable to create certificate
file /etc/cups/certs/0 - File exists


I would be really grateful for any guidance.

Best

Mack

You had the socket://ip.here:9100 part correct [it's not a 'windows'
printer]

However, you have a problem elsewhere. Check for 'AddCert' commands in
cupsd.conf

Hi Domink,

Thanks for your reply.

I couldn't find any. I grepped my entire /etc/cups dir for AddCert and
nothing shows up. But am I doing something wrong? Do I even need a
certificate to print to this machine (I don't have one)?

Thanks for any help,

Mack

Then check for ServerCertificate and ServerKey options. You don't _need_ ssl
for printing at all.
