Special Notes
1.
UPC and EAN bar codes are not affected by the different types of narrow to
wide ratios. Instead, the <ESC>D command adds descender bar to these codes
where needed to meet UPC specification. The <ESC>BD command puts
descender bars and human readable text below the symbol.
2.
The Code 128, UCC 128, MSI, and Code 93 bar code are not affected by the
narrow to wide ratios.
3.
The Codabar and Code 39 bar codes are affected by the Character Pitch
command. The command must be placed before the Bar Code command.
4.
See Appendix B for more specific instructions and detailed information
regarding individual bar code symbols.
5.
Because
of
their
unique
characteristics, two-dimensional symbols are covered
separately.
6.
For UCC128, the FNC1 code is automatically inserted and the Mod 10 and Mod 103
check digits are automatically calculated.
7.
For the MSI bar code, the check digit is not automatically calculated.
8.
To select UPC-A, 11 digits of data are sent. The printer adds a “0” and
automatically generates the check digit. If 12 digits of data are sent, the printer assumes
an EAN-13 symbol and automatically generates the check digit. The last digit of bar
code data is a modulo 10 check digit. If 13 digits of data are sent to the printer, the
check digit is not created and must be supplied by the programmer. It must be the last
character of the 13 digit string.
