This happened again, but on a different computer running Ubuntu 12.04. I was having printer trouble and I noticed that the make and model showed up as simply "Local Raw Printer". I attempted to change it to the MFC-7220 but I was unable to click apply on the "Existing Settings" page. I tried the flow a second time and the same thing happened. Then I tried it from "system-config-printer --debug" to get the information you wanted, but that time the Apply button _was_ enabled. I then cancelled and went back to do it normally (i.e., not running it from the terminal with --debug) and Apply was still enabled. So somehow the --debug run magically fixed things without actually "applying" any change. :/
I've attached the --debug output from the run that magically fixed things. The "No installable options" line is the last one that appeared before cancelling. ** Attachment added: "debug.log" https://bugs.launchpad.net/ubuntu/+source/system-config-printer/+bug/782005/+attachment/3580565/+files/debug.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/782005 Title: Cannot click Apply on "Existing Settings" screen of "Change Driver" wizard in printer properties To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/system-config-printer/+bug/782005/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
