In cups, I defined 2 setups for my printer: "standard" for one-sided printed and "duplex" for printing on both sides of the paper sheed. Depending how the result should be, I chose either "standard" or "duplex" as the printer to print to in the applications. This works well with libreoffice and okular and worked in former times for firefox and thunderbird as well - but it doesn't any more.
All printers shown in firefox and thunderbird always show the same setup: Either all are set up for one-sided printing or all are shown as duplex. If I change the setting for one specific printer, it affects all printers (only in ff and tb). Is that a bug or a feature?
I want the per printer definition back for ff and tb ... can you help me with that (can I put a specific entry in prefs.js or user.js to re-enable the per printer setting for duplex printing)?
