Configuring the Printer 3–60
Stop Bit
The Stop Bit parameter sets the number of stop bits in the serial data word.
Either one or two stop bits can be selected. The setting must match the
corresponding stop bit setting in the host computer.
Parity
The Parity parameter can be set for odd parity, even parity, or no parity. The
setting must match the corresponding parity setting in the host computer.
Parity error handling is discussed further on page 4–12 in Chapter 4, Printer
Interfaces.
Bit 8 Function
The Bit 8 Function parameter controls how the printer interprets data bit 8 in
the serial data characters it receives from the host computer. You should set
this parameter according to the manner in which the host computer uses data
bit 8.
•
Font Select: This setting allows access to the extended ASCII character
set.
•
PI Line: This setting allows the host computer to use data bit 8 to
control vertical paper motion.
•
Ignore: This setting causes the printer to ignore data bit 8.
NOTE: Do not select the PI line setting of the Bit 8 Function parameter
unless the host computer uses bit 8 for paper control. Otherwise,
rapid vertical paper movement (“slewing”) might occur.
