Barcode Programming Examples
For barcode types EAN, UPC, Code 93, Code 128 and Postnet the printer
automatically adds start and stop characters.
S
Example for Code 39
For barcode type Code 39, 2 of 5 industrial and 2 of 5 interleaved the printer
adds start and stop characters only if they are not generated by the system.
type

ESC * z 0 V
For barcode type Codabar the application has to generate the start and stop

Following start and stop characters are accepted by the printer:

t, n, *, e, A, B, C, D
Note:
Following combinations (start / stop) are specified for Codabar, but not
checked by the printer:
(a / t) (b / n) (c / *) (d / e) (A / A) (B / B) (C / C) (D / D)
S
Error checking characters
Error checking characters are added by the printer only for barcode types
Code 128, Code 93 and Postnet. For all other barcode types the application
has to generate error checking characters and transmit them to the printer.
S
Unprinted areas
To ensure proper readability of a barcode unprinted areas in front and behind
the barcode are required. The printer does not insert these areas itself; the
amount of space has to be calculated by the application.
