lpstat [ioport] [jobID]
Example: lpstat prn
Display active and queued jobs and I/O port status for a given
ioport or jobID. Specifying one of these parameters will
shorten the output and focus on the particular I/O port or print
job specified.
cancel jobID
Example: cancel d1prn-10
Remove a job from an I/O port queue. Use lpstat to find a
particular job ID first.
start fox|tts|loopb prn
Example: start fox prn
Begin a debugging test on one of the I/O ports on the NIC. The

troubleshooting hardware as long as the
attached printer supports text output.
tts A continuous stream of Gandalf 400C
TTS-compatible text sent to the attached
printer.
loopb Loopback test. Any input characters from the
device attached to the I/O port is echoed
back.
stop all|prn
Stop an output test on an I/O port.
disable ioport|destination
Example: disable prn
Disable an I/O port so that queued jobs are not printed, or
