cups printer instances not usable from gtk applications

[Patrick Pfeifer]

This (http://lists.opensuse.org/opensuse-bugs/2009-02/msg05856.html) bug on suse summarizes the problem.

I have once filed a bug upstream (http://bugzilla.gnome.org/show_bug.cgi?id=582747) which never got any attention.

My suggested workaround in the upstream bug would at least prevent one bad effect the bug is having if you define cups "instances" in your /etc/cups/lpoptions or ~/.cups/lpoptions - either using old kde 3.5 print configuration dialog or "lpoptions" command line.

Read the loptions man page to learn about cups "instances". They are really useful. If anybody knows an alternative I'd be happy to learn about it as well. Multiple "queues" (printers) for the same "device URL" are not an alternative, as at least /usr/share/system-config-printer/system-config-printer.py (System->Administration->Printing) doesn't seem to allow setting up multiple printers with the same device file due to a cups error (client-error-not-possible) occurring if you try (at least for the cnij_usb: backend I'm using).

If the cups instances are here to stay and somebody gave me some tips on how to get my code accepted by upstream I'd maybe take some effort to implement instances in the gtk libprintbackend-cups library.

But there is some other printing dialog efforts going on. E.g. "Common Printing Dialog" (https://wiki.edubuntu.org/CommonPrintingDialog) On this (https://www.linuxfoundation.org/en/OpenPrinting/OpenPrinting_Summit_San_Francisco_2009) page you find some nice slides (https://www.linuxfoundation.org/images/4/4d/CommonPrintingDialogLF09.pdf) about it. Does anybody know if there are any useable results from this project yet ?
