Bar Codes

Valid inputs for the bar code field b are letters: uppercase letters will print a human-readable text
below the bar code; lowercase letters will only print the bar code. For example, entering a 'p' in the
b field selects the Postnet bar code. Because the Postnet font does not provide human-readable
data, the uppercase P is not valid. Other bar codes without a human-readable counterpart include u
(MaxiCode) and z (PDF417) – for additional model-specific restrictions see Appendix F.
For module-based bar codes, field d is the narrow bar width in dots (bar code module size). For
consistent results in all rotations for bar codes of this type, field d and field c must have the same
value. For ratio-based bar codes field c is the wide bar width in dots (the numerator); field d is the
narrow bar width in dots (the denominator). See Appendix G for specific bar code information and
variations in record format field usage.
The eee height field represents the bar code (symbol) height. The valid range (001 to 999)
translates to bar heights ranging from .01 inch (.254 mm) to 9.99 inches (253.7 mm). For bar codes
that require additional specified parameters, use the jj...j data field as the location for these
parameters. See the specific bar code for details in Appendix G.
Field
1, 2, 3 and 4
a
A to Z and a to z (except P, u, v, z), or Wna where n is 1 to 9 and
b [bb]
a is A to S and a to s. No n is an implied 1.
1 to 9, A to Z, and a to z
c
1 to 9, A to Z, and a to z
d

eee
0000 to 9999
ffff
See Appendix K.
gggg
Valid ASCII character string up to 255 characters followed by a
jj...j
termination character.
Placing a 0 (zero) in both c and d will cause the printer to use the default bar code ratio or module
size. Placing a 000 (zero) in the symbol height field causes the printer to use the default bar code
height. See Appendix F for default ratios and sizes.
