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 bars to these codes where needed to meet UPC specifi-
cations. The <ESC>BD command puts desender bars and human
readable text below the symbol.
2. The Code 128, UCC 128, MSI, and Code 93 bar codes are not
affected by the narrow to wide ratios.
3. The Codabar, Code 39, Industrial 2 of 5, and Matrix 2 of 5 bar codes
are affected by the Character Pitch command. This command must
be placed before the Bar Code command.
4. Because of their unique characteristics, two-dimensional (2D) sym-
bols are covered separately.
5. For UCC128, the FNC1 code is automatically inserted and the Mod
10 and Mod 103 check digits are automatically calculated. For the
MSI bar code, the check digit is not automatically calculated.
6. The <ESC>D and <ESC>BD commands are not valid for the MSI,
Code 128, Code 93, UPC-E, Bookland, UCC128 and Postnet sym-
bologies.
7. 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 gen-
erates the check digit. If 13 digits of data are sent, the check digit is
not created and must be supplied by the programmer. It must be the
last digit in the 13 digit string.
8. See SATO Programming Reference: Appendix A PN 9001096 for
symbology specific formatting information.
