Dataproducts Submenu
IMPORTANT
The Dataproducts parameters in the printer must be set the same as the
Dataproducts 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 Dataproducts 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.
PI Ignored
The PI (Paper Instruction) signal is used to control vertical paper motion.
• Enable. Ignores the PI signal and treats the data as characters or control
codes.
• Disable. Causes the printer to interpret the eight data lines as VFU
commands when the PI signal is true.
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.
