F28 cups not printing: using usb to paralell port adapter cable with HP LaserJet 1100 printer
After sending a job to my printer there is no printer activity. Checking the printer queue shows 1 job processing; however, the printer shows no activity.
So I check the logs using the following command:
journalctl -b -p err
In the journal error output, I find the entries related to cupsd:
cupsd[nnn]: [CGI] cups-brf must be called as root
cupsd[nnn]: [cups-deviced] PID 13104 (cups-brf) stopped with status 1!
Some relevant details:
- Fedora Linux version 28 - Server edition
- Kernel version (uname -r): 4.17.17-200.fc28.x86_64
- cups.x86_64 version: 1:2.2.6-18.fc28
- cups-filters.x86_64 version: 1.20.0-9.fc28
Although the following might not have any bearing, the printer is a HP LaserJet 1100 which has a parallel port connector connected to a parallel port to usb adapter with the usb end connected to the computer.
Does anyone else have this problem and have they solved it?
cups-brf
is the backend for a braille printer, and your error message is most likely irrelevant. Check the timestamp of the message.I would guess that the issue is with the parallel port to usb adapter. A google search for
"usb parallel port adapter linux"
shows some hits which might be relevant.
