Centronics Parallel Interface Configuration

The printer is configured at the factory according to the specified interface. However, the configura- tion is also user selectable. The following configuration parameters can be verified or changed as nec- essary to meet specific application requirements:

•Data Bit 8 (enable or disable)

•Data Polarity (standard or inverted)

•PI line (enable or disable)

•Response Polarity (standard or inverted)

•Latch Data On Leading or Trailing Edge of Strobe

These parameters are displayed under the Application Compatibility/Host Interface/Centronics sub- menu selectable from the control panel. Refer to the Control Panel Configuration Diagram in the Con- figuration chapter for information on selecting the various parameter values.
