Centronics Interface
IMPORTANT
The Centronics parameters in the printer must be set the same as the
Centronics interface in the host computer. Otherwise, the printer might
not work online, and data characters from the computer might not print
or might print as “garbled” text.
The Centronics submenu provides the options and settings available to
configure the interface as required for your application. These options and
available settings are outlined in the following paragraphs.
Data Bit 8
• Enable. Allows access to the extended ASCII character set.
• Disable. The printer interprets bit 8 of each incoming data character as a
zero, regardless of its actual setting.
Data Polarity
The Data Polarity parameter must be set to match the data polarity of your
host computer.
• Standard. Does not expect the host computer to invert the data.
• Inverted. Expects the data received on the data lines from the host
computer to be inverted. Ones become zeros, and vice-versa.
