Chapter 4 Emulation Menu
Offpage Errors
• Disable. Does not report errors for elements that start or end beyond the
right edge of the page.
• Enable. Reports errors for elements that start or end beyond the right
edge of the page.
Barcode Errors
• Enable. An error message will print when invalid bar code data is
encountered.
• Disable. Code V will not print an error for illegal bar code data; the bar
code will be skipped.
Ignore / DB8 Setup
Following are several options which define character filtering and data bit 8.
Ignore Nulls
• Disable. None of the null characters (hex 00 or 80) are ignored.
• Enable. Null characters are filtered out of the data stream.
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 When Barcode Errors is disabled, the Code V emulation will try to make
the best use of invalid data by either truncating extra digits or adding zeros
to the end of bar code data to meet minimum data length requirements for
some bar codes. Not all errors will be corrected.
Note Data bit 8 is interpreted as either data bit 8 or the 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.
