Which of the following are valid commands to affect your systems printing

Hiroshi T.Jun 27, 2026

The correct answers are A, B, and D. lpq queries the print queue so you can see pending jobs and their status. lprm removes a job from the queue, which directly affects what your system will print. lpr submits a file to the printer, which is the most direct way to affect printing. Options C and E, lpstatus and lpio, are not standard LPD or CUPS utilities and do not appear in the Linux man pages or the LPI 102-350 objective documentation, so they are distractors.

Picked C and E first, but lpstatus and lpio are not real commands.

Honestly my first instinct was to mark C and E as valid because they sound like they fit the naming pattern, lpstatus sounds like something that would show you queue status and lpio sounds like it could handle input/output redirection for print jobs. What changed my mind was thinking back to the actual commands I used when we had a shared HP LaserJet on the floor and someone's 400-page PDF was stuck at the top of the queue. The real toolkit is lpq to view the queue, lpr to send a job, and lprm to yank a stuck job out, those are the three you actually reach for. lpstatus and lpio are not real commands, the exam is testing whether you know the actual CUPS/LPD toolset versus plausible-sounding fakes.
