^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.
Format:^B7o,h,s,c,r,t
Parameters:
o= orientation
Accepted Values:
N = normal
R = rotated 90 degrees(clockwise)
I = invented 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.
