I updated CUPS and I cannot print to my USB laser printer. The web
interface shows the following:

hp_LaserJet_1160Le (Default Printer) "Unable to open USB device
"usb:/dev/ulpt0": Permission denied"
    Description: Hewlett-Packard LaserJet 1160Le
Location: Den
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


if the printer runs fine as root you know it's likely a
permission-problem

What's the best way to run it as root? When I log into the CUPS web interface as root and try to print a test page, it gives me the message I posted above. If, as root, I try to print a Postscript file via lp, it does nothing.

Thank you all again for your assistance._______________________________________________

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 to make the fix permanent:

[system=10]
add path 'unlpt*' mode 0660 group cups
add path 'ulpt*' mode 0660 group cups

Don't forget to restart devfs.

HTH,
Micah
