The printer communicates through the display and the lights on the control panel. The display shows status information, menus, help information, and error messages. The Ready, Data, and Attention lights provide at-a-glance information about the printer state.

ENWW Control-panel overview 9

You can perform most routine printing tasks from the computer through the printer driver or any software program. Use the control panel to access printer features that the printer driver or software program do not support. Any changes that you make from the computer override the printer control-panel settings. For information about using the printer driver, see

Printer software on page 12.
