Unix serial printer, or Unix pseudo printer (a printer attached to a terminal), loses print configuration or prints sporadically.

Solution:  As Superuser, run “stty sane < /dev/tty_device_of_printer” without quotes.

Where tty_device_of_printer is the serial node the printer is attached to.

For example stty sane < /dev/ttya09  for a serial printer attached to ttya09.

NOTE:  Superuser commands can only be run by authorized personnel.
