Special Notes 1. UPC and EAN bar codes are not affected by the different types of narrow to wide ratios. Instead, the D command adds descender bar to these codes where needed to meet UPC specification. The 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. 16
