^B7
PDF417 Bar Code
Description: The ^B7 command is a two-dimensional, multi-row, continuous
stacked symbology. PDF417 is capable of encoding over 1,000 characters per bar
code. It is ideally suited for applications where large amounts of information are
required at the time the bar code is read.
The code consists of 3 to 90 stacked rows. Each row consists of start and stop
patterns and symbol characters called “code-words.” A “code-word” consists of four
bars and four spaces. A three code-word minimum is required per row.
PDF417 has a fixed print ratio.
Format: ^B7o,h,s,c,r,t
Parameters:
o = orientation
Accepted Values:
N = normal
R = rotated 90 degrees (clockwise)
I = inverted 180 degrees
B = read from bottom up, 270 degrees
Default Value: Current ^FW value
h = bar code height for individual rows
Accepted Values: 1 to height of label
Default Value: Value set by ^BY
This number multiplied by the module equals the height of the
individual rows in dots. 1 is not a recommended value.
s = security level
Accepted Values: 1 to 8 (error detection and correction)
Default value: 0 (error detection only)
This determines the number of error detection and correction code-
words to be generated for the symbol. The default level provides only
error detection without correction. Increasing the security level adds
increasing levels of error correction and increases the symbol size.
c = number of data columns to encode
Accepted Values: 1to30
Default Value: 1:2 (row-to-column aspect ratio)
The user can specify number of code-word columns given control over
the width of the symbol.
