Your error_log shows
/usr/bin/pdftops: Permission denied
Probably your installation of the poppler-utils package is broken. Reinstall it with
sudo apt-get install --reinstall poppler-utils
If this command does not work, poppler-utils is perhaps not installed at all. Do
sudo apt-get install poppler-utils
in that case. After having done so, running the command
pdftops -h
should show a help message and not "Permission denied" or "Command not found". If you get the help message, clear the print queue with
cancel -a
and try to print again. Does it work now?
