As of latest unstable channel at the moment of writing (6221af50), CUPS+gutenprint is broken for me in the following ways:
1. Autodetection of a (USB) printer does not work. Nevertheless, CUPS usb backend correctly identifies a printer (and gives a URL) when ran directly. Access rights for /dev/bus/usb-node seems to be right (664 root/lp, though with some strange additional ACL granting write to my user, too). 2. If I add printer via "lpadmin" using URL generated by a backend, I cannot supply a PPD file for it. If I try to give CUPS a PPD file generated by "cups-genppd.5.2" (either via web interface or "lpadmin"), it fails with "No such file or directory". Of course, the file does exist, and when I try to point "lpadmin" to a really non-existent place, it fails with a slightly different error (same no-such-file, but with path added this time). I use https://nixos.org/wiki/Printers guide for my setup -- it worked nice before the Big Update in the channels (maybe a week ago) which also bumped CUPS' version. I don't have practically any time for researching this (and a lot of other things, too -- deadlines!) before the New Year, but after that I'll probably dig into it. It would be very nice for someone with a USB printer to share his experience -- I don't know if this is a Nixpkgs bug or my problem caused by something. If this is really a bug, it probably affects 14.12 too, and is a fairly serious thing in my opinion. -- Nikolay. _______________________________________________ nix-dev mailing list [email protected] http://lists.science.uu.nl/mailman/listinfo/nix-dev
