lpq

lpq [options] [+interval]

Check the print spool queue for status of print jobs. For each job, display username, rank in the queue, filenames, job number, and total file size (in bytes). We document the CUPS printing system here; other versions will vary slightly.

Options

-a

Report on all printers listed in the server's printcap database.

-E

Use encryption when connecting to a print server.

-l

Verbose mode. Print information about each file composing a job. Use -l multiple times to increase the information provided.

-P printer

Specify which printer to query. Without this option, lpq uses the default printer, normally set through lpadmin.

+interval

Check the queue every interval seconds until it is empty. For example, +10 reloads the queue every ten seconds.
