You send the job to the printer, what next? Well, the print job can be checked to see if it's in fact in the queue and being processed by the print server. After you've sent a job to the printer, especially if it is a network printer located a distance away, you will want to verify the completion of a job so that you know if you need to send it again or check for other problems.
To check the status of a job, you'll want to look at the queue for the printer to which you submitted the job. You do this with the lpq -P<printer name> command. Once again, if there is only a single printer on your system, you can probably just issue lpq by itself.
