Data Bit 8
•
Enable. The PI line is not passed directly from host to printer;
all 8 bits are used for data bits, and characters in the hex 80-FF
range can be accessed.
•
Disable. When the host PI line is enabled, data bit 8 internally
indicates PI line status. To use the PI line, disable data bit 8,
and enable the Host PI configuration option (under the PI
Control option, below).
NOTE: Data bit 8 is interpreted as either data bit 8 or PI signal, but
Conversely, when data bit 8 is disabled and the PI signal is used,
data bit 8 of the data is reserved for use as the PI function, and you
cannot access characters in the hex 80-FF range. Therefore, to
access characters in the hex 80-FF range, data bit 8 must be
enabled.

never both. When enabled as data bit 8, data bit 8 has
priority over the PI signal, and all data above hex 7F is
used to access character data and not to interpret PI line
data.
