IGP/VGL Emulation
Ignore CH#1
Specifies character 1 for the character filtering option. Valid decimal values
are from 0 through 255.
Ignore CH#2
Specifies character 2 for the character filtering option. Valid decimal values
are from 0 through 255.
Data Bit 8
•
Enable (default). 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 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.
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.
Font Set
The Font Set specifies which language is currently selected for use with the
VGL. Refer to “IGP/VGL Font Set Menu” on page 144 for available selections.

must be disabled to transmit the PI line to the printer.
