I have found out what the problem is. system-config-printer tries to crate a print queue with an URI which contains double quotes. Same as if you try the following command in a terminal window:
lpadmin -p testprinter -E -v dnssd://Xerox%20WC%205638%20"CHARLESMEREDITHHOUSE_207"%20%40%20Arijit%20Nandi%E2%80%99s%20Mac._ipp._tcp.local/cups CUPS complains with "Bad device-uri" and creates a queue pointing to /dev/null. ** Changed in: system-config-printer (Ubuntu) Status: Incomplete => Triaged -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/851189 Title: There was an error during the CUPS operation: 'client-error-not- possible' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/system-config-printer/+bug/851189/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
