[SOLVED] Can't get printer to work

chrsprkr3 · 2010-06-04 16:29:35

This is driving me batty. I simply cannot get printing to work on my HP LaserJet 5L via LPT0.

1) A freshly cleansed cups error_log has two entries when I start the cups daemon:

E [04/Jun/2010:09:27:05 -0700] Unable to open listen socket for address :::631 - Address family not supported by protocol.
E [04/Jun/2010:09:27:05 -0700] Unable to set ACLs on root certificate "/var/run/cups/certs/0" - Operation not supported

2) I've opened up my cups config file ridiculously wide hoping that it was simply a permissions problem.

</Policy>

3) I can print a test page from the CUPS web admin at http://localhost:631

4) When I try to print from a "normal" application (say Kate or OpenOffice), it just does nothing. It does not error, it does not add any entries to the error log. Nothing.

What am I missing?

EDIT: I should also add that I did an nmap on the local interface, and port 631 is open. E.g.:

[cparker@frankenputer ~]$ nmap -sT localhost

Starting Nmap 5.21 ( http://nmap.org ) at 2010-06-04 09:45 PDT

Well, I've managed to get local printing to work. I overwrote my cups conf file and replaced it with the default version, and started again adding additional permissions.

My problem now is that I get authorization error when I try to print from another computer on the network. Specifically this is the error message:

"POST /printers/HP_LaserJet_5L HTTP/1.1" 200 64587 Print-Job client-error-not-authorized

So what now?

My newly revised cupsd.conf file is below...

I had a brain-wave. Previously I couldn't open the printer in KDE's system settings dialog. The dialog would just sit forever thinking. It occurred to me that since I was able to print, maybe the dialog would open. And it did.

For my next step, I opened system settings as root, went into the printer configuration, went onto the policies tab and then changed the user and group permissions to "Allow printing for everyone except these users." and emptied the field. So basically everyone is allowed to print. I don't know what specifically that changed, and if I find it I'll post back. But for now I'm able to print.
