A few things to remember. First, the printer has no reliable way to communicate back to the print server that it is printing, jammed, out of paper, etc. You will have to pay attention to the printer itself. If a print job is slow, then the lpq command will show the printer as stalled, when in fact it might still be printing. If something is wrong, then an angry orange light will flash on the printer and the LCD will explain the problem. If it is a jam, open the front door and look up the jam location on the table. If you know where the jam is already, you have to open the door anyway or else the printer won't know you cleared it.
