Preamble/Postamble
Similar to the Prefix/Suffix, up to 22 ASCII characters may be added as a preamble (in a position before the bar code data) and/or as a postamble (in a position following the bar code data) as indicated in Figure

Example: Setting a Postamble
In this example, we’ll set a postamble for all symbologies.
1.Determine which ASCII character(s) are to be added to scanned bar code data. In this example, we’ll add the percent character (‘%’) as a postamble.
2.Scan the START bar code.
3.Scan the SET POSTAMBLE CHARACTER(S) bar code.
4.Reference Appendix A, ASCII Conversion Chart, to find the hex value assigned to the desired character. The corresponding hex number for the ‘%’ character is 25. To enter this selection code, scan the ‘2’ and ‘5’ bar codes from Appendix B,
5.Scan the SET bar code to accept the digits scanned.
6.Scan the TRANSMIT POSTAMBLE bar code to allow transmis- sion of the postamble.
7.Scan the END bar code to exit Programming Mode.
8.The resulting message string would appear as follows:
Scanned bar code data: | 12345 |
Resulting message string output: 12345%
