Mac OS Printer Driver
The printer driver controls the printer according to the commands from an application. Making settings on the printer driver provides the best printing results. You can also check the status of the printer or keep it in top operating condition using the printer driver utility.
Click Page Setup or Print on the File menu of your application. If necessary, click Show Details (or 
) to expand the print window.
Depending on the application being used, Page Setup may not be displayed in the File menu, and the operations for displaying the print screen may differ. See the application's help for details.
Select System Preferences from the 
menu > Printers & Scanners (or Print & Scan, Print & Fax), and then select the printer. Click Options & Supplies > Utility > Open Printer Utility.
