1. Open the Printers folder, then right-click the icon of your printer.
2. Click Printing Preferences on the shortcut menu that appears, then right-click anywhere in the
driver.
If About is displayed in the shortcut menu that appears, click it. If a message box with the words
"Unidrv Printer Driver" appears, you must reinstall the printer software as described in the Setup
