Hello Daniel

The all-in-one printer is connected via USB.  The following versions are
installed:

net-print/hplip-3.9.12-r1
net-print/cups-1.3.11-r1
      
Try to blacklist & rmmod the usblp module. I had to do that for my HP
USB printer to work. Whenever usblp module was loaded, printing
failed... I don't know if it applies to your printer as well, but it's
something easy to try. :)


    
I do not own an all-in-one printer so I can not test, but if Paul's suggestions
do not work can you tell me the permissions of your device.

lsusb
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 005 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 002: ID 03f0:1712 Hewlett-Packard Printing Support
Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

lsusb tells you to which bus the printer is attached. In my case it is Bus 001
and Device 002 so I have the following device /dev/bus/usb/001/002

ls -al /dev/bus/usb/001/002
crw-rw-r-- 1 root lp 189, 1 20. Apr 19:05 /dev/bus/usb/001/002

There should also be a /dev/usb/lp0

ls -al /dev/usb/lp0
crw-rw---- 1 root lp 180, 0 20. Apr 19:05 /dev/usb/lp0

Do you have the same permissions or do they differ?

Paul,

I checked for lsusb and could not find it...therefore I checked my kernel source, and found usb printer support, which I removed.  This has not fixed the problem.

Daniel,
