Refer to “Parallel Submenu” on page 107 for Centronics parameter descriptions and information on selecting values for the following parameters:

Data Bit 8 (enable or disable)

Data Polarity (standard or inverted)

Strobe Polarity (standard or inverted)

Response Polarity (standard or inverted)

Busy on Strobe (enable or disable)

Latch Data On Leading or Trailing Edge of Strobe

Prime Signal (enable or disable)

TOF Action (reset or do nothing)

Buffer Size in K (1-16)

Some application programs require a unique configuration. If the printer is not working properly in the configuration you have selected, contact an authorized service representative.
