My situation was similar: 10.04LTS print server and 12.04LTS LTSP thin clients and server. Was trying to off-load the printing services from my ltsp server to an existing 10.04 machine. Once configured, thin clients could not discover printers in any applications (except Chromium Browser). Upgraded cups on 10.04 machine using source to 1.6 with no change. Moved configuration files (/etc/cups) and ppd's to 12.04 server (cups 1.5) and thin clients saw all printers. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to cups in Ubuntu. https://bugs.launchpad.net/bugs/992468 Title: network print : no possible with 12.04 Status in “cups” package in Ubuntu: Fix Released Status in “system-config-printer” package in Ubuntu: Fix Released Status in “cups” source package in Precise: Fix Released Status in “system-config-printer” source package in Precise: Fix Released Bug description: Same of a lot of users who upgrade 11.10 to 12.04, it is now impossible to connect printer whith network. before report bug: I try install printer with several versions of driver: hplip 3.11.7 old version hplip 3.12.2 native 12.04 hplip 3.12.4 latest version I report bug to cups.org with the error log of the page http://localhost:631/admin they say me : "Please re-contact your Linux distributor for this - the error message in the log indicates that the driver (or configuration of CUPS) you are using is not accepting the print file, so we never even try to send the job to the printer (it is never processed)."
