[Touch-packages] [Bug 1815307] Re: ipp printer isn't shown automatically - adding it errors with a CUPS internal error
Michael Sweet was not able to reproduce this bug with the Canon printer he got at Apple. See https://github.com/apple/cups/issues/5512 Please post in this bug report to directly interact with Michael. Before doing so, get a setup of Disco (upcoming Ubuntu 19.04) and check whether your problem still exists. Disco contains all the fixes mentioned in the upstream bug reports. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to cups in Ubuntu. https://bugs.launchpad.net/bugs/1815307 Title: ipp printer isn't shown automatically - adding it errors with a CUPS internal error Status in cups package in Ubuntu: Triaged Bug description: System: Ubuntu 18.04 system-config-printer version: 1.5.11-1ubuntu printer: Canon iP7250 I expect to be able to see the printer in the panel just as 'lpstat -l -e' or 'driverless' can see them, without the need to especially add a new printer.

@fargoth, sorry for that comment. I was wrong. What got actually fixed was another thing which I observed during the investigations for this bug.

[Touch-packages] [Bug 1815307] Re: ipp printer isn't shown automatically - adding it errors with a CUPS internal error
A similar report got also to CUPS upstream: https://github.com/apple/cups/issues/5512 and it seems that there is either a firmware bug in the AirPrint- supporting Canon printers or some problem with the client-side IPP implementation (which is in libcups, part of CUPS). Michael Sweet, author of CUPS, will get a Canon printer on the coming Wednesday for further investigation. Moving this bug to CUPS, system-config-printer has nothing to do with it. ** Bug watch added: github.com/apple/cups/issues #5512 https://github.com/apple/cups/issues/5512 ** Package changed: system-config-printer (Ubuntu) => cups (Ubuntu) ** Changed in: cups (Ubuntu) Importance: Undecided => Medium ** Changed in: cups (Ubuntu) Status: New => Triaged -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to cups in Ubuntu. https://bugs.launchpad.net/bugs/1815307 Title: ipp printer isn't shown automatically - adding it errors with a CUPS internal error Status in cups package in Ubuntu: Triaged Bug description: System: Ubuntu 18.04 system-config-printer version: 1.5.11-1ubuntu printer: Canon iP7250 I expect to be able to see the printer in the panel just as 'lpstat -l -e' or 'driverless' can see them, without the need to especially add a new printer.
