[SOLVED] Printing with different cups version on client and server

hadack · 05-09-2015, 07:42 AM

I used to print from my slackware64-current machine on a slackware64-14.0 server and it was working fine. After cups has been upgraded to version 2 in current i cannot print anymore. The cups web interface cant see any printer on the server and system-config-printer sees my printer after i created /etc/cups/client.conf:

Code:

ServerName 192.168.1.2/version=1.1

but when i try to print it says something like "cannot get information from printer" and prints this error in the console:

Code:

Traceback (most recent call last):
  File "/usr/share/system-config-printer/system-config-printer.py", line 1666, in on_edit_activate
    self.dests_iconview_item_activated (self.dests_iconview, paths[0])

    e == cups.IPP_AUTHENTICATION_CANCELED):
AttributeError: 'module' object has no attribute 'IPP_AUTHENTICATION_CANCELED'

Any ideas to make it work or do i have to upgrade/downgrade one of the versions?

It should work. I have cups 2.0.2 working with 1.5.4, but I have not tried any earlier versions.

Have you applied the cups updates from May 4th, and have you configured and started the cups browsing daemon? (See /etc/cups/cups-browsed.conf and /etc/rc.d/rc.cups-browsed)

After applying the big April 21 update my workstation stopped seeing any of my networked printers, which are all shared with earlier versions of cups. I applied the May 4th updates and spent some time cleaning cruft out of my cupsd.conf (which got rid of a few warnings that were appearing in the log files), before finally realizing that the browse daemon was necessary. Once that was running everything works perfectly.

It works now, I did not realize that there was a new start script ind the cups-filters package, so starting this one made the web interface work, but it was still needed to clean up the config files to make actual printing work.

Thanks a lot!
