Stange Cups Problem: "/dev/lp0": Permission denied

[macsek]

Well, it seems, that cupsd runs as lp user, lpadmin group, and cannot
open /dev/lp0, /dev/usb/lp0. I modified these devices to have lp/lp
(user/group) instead of root/lp
(/etc/udev/permissions.d/udev.permissions):




Code:
--------------------
    

  printers/*:lp:lp:0660

  usb/lp[0-9]*:lp:lp:0660

  usb/legousbtower[0-9]*:root:root:666

  lp[0-9]*:lp:lp:0660

  parport[0-9]*:lp:lp:0660

  irlpt[0-9]*:lp:lp:0660

  usblp[0-9]*:lp:lp:0660

  
--------------------




(Pull out and replug USB cable to check, or  chown lp:lp /dev/lp0.)



Then it works without having to set 0666 or chmod o+rw on devices -
which is bad thing.



(First I tried root/lpadmin, but it did not work...)



I just wonder how it is supposed to work...
