Ignore Chars

Disable. Character filtering is not enabled.

Char 1. Character 1 will be filtered. Select the option “Ignore Ch#1” to specify character 1.

Char 2. Character 2 will be filtered. Select the option “Ignore Ch#2” to specify character 2.

Char 1&2. Characters 1 & 2 will be filtered. Select the options “Ignore ch#1” and “Ignore Ch#2” to specify values for these characters.

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. 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.
