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

['Forum Post]

Problem still exists in Kubuntu 5.10, Breezy Badger

The solution has changed somewhat due to changes in udev. 

The problem can be recognised in the print tool by looking at the IPP
report, where it says ""/dev/lpx": Permission denied", where x ranges
from 0 to 9. 

Indeed, on "ls -l /dev/usb/lp*" one sees that only root has access, so
cupsd not.



To solve: open /etc/udev/permissions.rules

and do the changes: 

BUS=="usb", KERNEL=="lp[0-9]*", GROUP="lp"

into 

BUS=="usb", KERNEL=="lp[0-9]*", MODE="0660", OWNER="lp", GROUP="lp"



and 

SUBSYSTEM=="printer",     GROUP="lp"

into

SUBSYSTEM=="printer",   OWNER="lp",     GROUP="lp"



This solved the problem for me. Switch of the printer, switch back on,
and now "ls -l /dev/usb/lp*" shows that lp has the required access.

Go to the print tool, restart the printer, and yes, the jobs start
flowing! :razz:
