Normally an app does not need to care of Collate supported by the printer or not. It should simply send one copy of the job and the IPP attributes for the number of copies and for collate on/off. Then there is only one CUPS job and CUPS handles hopw it gets printed, especially whether the printer does hardware copies/collate and if not sending data repeatedly within this one job. An app should never send more than one job to CUPS when the user has clicked "Print" once. This is a bug.
Page management (copies, collate, even/odd pages, selected pages, mirrored print, N-up, ...) is handled by CUPS, so please let the desktop apps send one copy of the full document along with the appropriate IPP attributes to control page management. CUPS does the rest then, in the same way as for the other apps. Only exception couls be selected pages here, to not send 100 pages to CUPS if the user only wants 1 page. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1025839 Title: Printing multiple copies submits multiple separate jobs (should submit one job) To manage notifications about this bug go to: https://bugs.launchpad.net/df-libreoffice/+bug/1025839/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
