I think I may have narrowed down the issue. I changed the cupsd.conf LogLevel to 'debug'.
When adding a printer via SMB with 'requires authentication' ticked and filled out I noticed that the logfile says: CUPS-Add-Modify-Printer client-error-not-possible: Bad device-uri "smb://myusername:MyComplexpAss/1/2/3@/server/PRINTERSHARENAME"! My Password has forward-slashes in it and so does the device URI. From what I can see, they're not being escaped properly which may be causing the 'Bad device-uri' error. -- Hardy Heron: Adding SMB printer fails https://bugs.launchpad.net/bugs/218032 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
