Debugging

Check the printer status

If your printer does not print, first check printer status `lpstat -p boomaga.

Read CUPS logs

If your Boomaga printer is enabled you can check the log for errors. If you're on systemd, run

sudo journalctl -f -u cups.service | grep -i boomaga,

or read log files, run

sudo tail -f /var/log/cups/error_log | grep -i boomaga.

And print test job to Boomaga printer: date | lpr -P boomaga

Debug mode

For better debugging, enable debugging in CUPS: sudo cupsctl --debug-logging

Later, you can disable debugging: sudo cupsctl --no-debug-logging

SELinux

Red Hat is constantly tightening the rules for SELinux, this can cause problems with Boomaga. You can verify this by temporarily disabling SELinux. To get the current SELinux status run

sudo sestatus

To disable SELInux and print test job run:

sudo setenforce Permissive 
date | lpr -P boomaga

Later, you can enable SELinux: sudo setenforce Enforsing
