I updated CUPS and I cannot print to my USB laser printer. The web

hp_LaserJet_1160Le (Default Printer) "Unable to open USB device

Description: Hewlett-Packard LaserJet 1160Le
Make and Model: HP LaserJet 1160 Foomatic/hpijs (recommended)
Printer State: stopped, accepting jobs, published.
Device URI: usb:/dev/ulpt0
are the permissions on /dev/ulpt0 correct ?
I have no idea what it is supposed to be.
%ls -l /dev/ulpt0
crw-r--r-- 1 root operator 0, 68 Jun 25 19:01 /dev/ulpt0

web interface as root and try to print a test page, it gives me

I had the same problem. chown ulpt0 to group cups and add group
write. That will fix it. I added the following to /etc/devfs.rules

chgrp cups /dev/ulpt0
chmod g+w /dev/ulpt0
I did not have a /etc/devfs.rules file, so I copied /etc/defaults/
devfs.rules to /etc/devfs.rules and added what you suggested at the
bottom of it.
add path 'unlpt*' mode 0660 group cups
add path 'ulpt*' mode 0660 group cups
Don't forget to restart devfs.
When I do
it seems like nothing happens. So, I rebooted my machine and the
group was back to operator. What am I doing wrong? Thank you so much
for your assistance with this.
