The control panel allows the user to input various functions. The display acts in concert with the indicator lights to inform the user of the printer's status. It shows the status of the printer, if it is warming-up, ready, in mid-function, or experiencing an error. More sophisticated printers allow the user to configure the status display to read in a variety of languages. Common controls on a printer include ~line-feed~, ~form-feed~, placing the printer ~on-line~, and configuring the paper size.
