## Understanding parallel-attached limitations

For parallel-attached printers without bidirectional communications, the default settings for the printer are displayed, not the actual printer settings. Only the settings that you change are sent to the printer when you click Apply Settings. To display the actual settings:

1. Install the bidirectional communications component included on the Software and Documentation CD.

2. Verify the associated driver has bidirectional communication enabled (look under the Ports tab in Print Properties).

The utility window status bar displays "Settings Status—Verified," indicating bidirectional communication.

Note: Bidirectional communication requires an IEEE 1284-rated parallel cable.
