You can change your printer setting by using your application software, your Lexmark printer
driver, the printer operator panel, or the remote operator panel available from MarkVision.
Note: Printer settings selected from a software application or driver override
default settings selected from the operator panel.
If there is a printer feature you cannot control from the application or printer driver, use the
printer operator panel or the remote operator panel available from MarkVision. Changing a
printer setting from the operator panel or from MarkVision makes that setting the user default
for all subsequent jobs sent to the printer. In most cases, settings you change from the
application or driver apply only to the job you are preparing to send to the printer.
