Alternatively, you can specify the print quality setting from your software printer driver. In this case, the drivers setting is used for the next print. During the print, the front-panel setting changes temporarily to that from the driver, and then resumes its previous setting again.

The exact printing process used by the printer varies not only with your print quality setting, but also with your specification of the media type (see page 2-3). Recommended combinations of print quality and media type are given in the table on page 2-5.

Recommended media types for various applications are given in the table on page 2-6.

General tips By choosing Fast, you will get draft-quality output in the shortest time. By choos ing Normal, and a suitable media type, you will get high-quality output in a reasonable time. By choosing Best, you will get the highest possible quality for the media type, but the printing time will be longer.

To change the print quality on the front panel

Use the front-panel Print Quality key to toggle between the three print quality settings.
