Appendix E: Printing Bar Codes

Using the bar-code feature, the following bar codes can be easily printed from the
IBM host.
Type
1
2
3
4
5
6
7
To print any of these bar codes, use the following format:
¬B<type>,<height>,<width>,<hr>,<chkd>,<ast>,<data>¬B
The bar code command string must contain all of these parameters, even if the
parameter is irrelevant for the type of bar code being printed. For example,
POSTNET comes in only one size, so any height or width specifications are
ignored—but they must be present anyway.
¬B: Identifies the string as a bar-code command string. ¬B must be placed at the
beginning and at the end of the string.
<type>: Specifies the bar-code type according to the table shown above.
<height>: Specifies the height of the bar code. Height is expressed in multiples
of 2.5 mm (approximately 1⁄10 inch). The height of the bar code can range
from 1 (2.5 mm) to 9 (22.5 mm) inclusive.
Height values are ignored if a POSTNET bar code is being printed, since
POSTNET uses one standard height. However, a valid value (1-9) must be
entered for the height parameter to ensure that the bar code command string
is complete.
<width>: Specifies the width of a bar code module. A module is defined as a
specific combination of bars and spaces used to represent a human-readable
character.
