It can.


cupsdisable  LJ4050N
cancel -a -x  LJ4050N

tree /var/spool/cups
	/var/spool/cups
	└── [root            4096]  tmp

	1 directory, 0 files

printing fails from all apps, for all files.
here's an example of printing a simple text file

	cat test.txt
		test

from Kate editor.  As <user>,

--> Kate:Print "test.txt"

	NO OUTPUT TO PRINTER !!


tree /var/spool/cups
	/var/spool/cups
	├── [root           13461]  d00743-001
	└── [root            4096]  tmp

	1 directory, 1 file

cp /var/spool/cups/d00743-001 /tmp/print-job-data.save
chmod a+r /tmp/print-job-data.save

cancel -a -x  LJ4050N
cupsenable  LJ4050N

printing with gs

	gs -r50 -sPAPERSIZE=letter -dFIXEDMEDIA /tmp/print-job-data.save

output's OK
