Appendix C: Bar codes
C-2
We do not guarantee that bar codes printed with these commands
can be read by all bar code readers. Before you use these commands
we recommend that you test whether your bar code reader can read
the printed bar codes.
Bar Code Types
You can print seven different types of bar codes. The bar codes are
selected by the command sequences listed below.
The command sequences are:
EAN Codes
->
EAN 8
(IAN8, JAN8)
->
EAN 13
(IAN13, JAN13)
UPC Codes
->
UPC-A
->
UPC-E
Code 39
Code 128
Interleaved 2/5
ZIP Code
->
ZIP Code Bar Code
With all bar codes, except the bar code UPC-E, it is possible to calcu-
late and print a checksum.
Because of the 24 dot matrix printing technique the smallest bar
code size that can be printed is a Low-Density Code and/or an en-
largement factor of 1.35.
EAN, UPC and Code 128 type bar codes can be enlarged in seven
steps. Code 39 and Interleaved 2/5 type bar codes the black and/or
the white area can be enlarged in seven steps by two parameters.
However, it is recommended that both areas be enlarged by the
same value.
Positioning
When designing a bar code ensure that the character position of the
bar code is absolute in order to avoid rounding and positioning er-
rors.
