W1f / W1F: Aztec
Valid Characters: All ASCII characters, depending upon the selected options.
Variable Length (W1f): This two dimensional bar code holds a large amount of data in a small area
and can provide a high level of error checking.
Specified Length (W1F): With a string four-digit length specifier, values 0x00 through 0xFF to be
included within the data strings without conflicting with the DPL format record terminators.
Syntax: a W1 b c d eee ffff gggg [hhhh] i jjj kk…k
Where:
Field Valid Inputs Meaning
a 1,2,3, and 4 Rotation
W1 W1 Fixed value, extended bar code set
b f and F Lowercase selects the Aztec bar code, variable length
Uppercase selects the Aztec bar code with a Byte Count Specifier
c 1 to 9, A to Z,
and a to z
Module size horizontal multiplier, 0 = default size. The c/d module
size parameters should be equal to produce a square symbol. When the
label command (Dwh) is used to generate larger text, then c and d may
be used to compensate and ensure a square symbol.
d 1 to 9, A to Z,
and a to z
Module size vertical multiplier, 0 = default size (See explanation for
‘c’, above.)
eee 000 No Effect
ffff 0000 to 9999 Label position, row
gggg 0000 to 9999 Label position, column
[hhhh] 0000 to 9999 Optional string length specifier. Field termination is set by this byte
count. This decimal value includes all of the data following this byte
count field, but does not include itself.
i 0, 1 Extended Channel Interpretation (ECI) mode; 0 = Disabled,
1 = Enabled
jjj 000 to 300 Error Correction (EC) / Amount (see table below), where:
000 – Default EC, approximately 23%
001 – 099 EC fixed value, expressed as a percent.
101 – 104 Compact core, 1 to 4 layers respectively.
201 – 232 Full size core, 1 to 32 layers respectively.
300 – Rune format, encodes three ASCII decimal digits 0-256;
scanner decode output is decimal number 0-256
kk…k 8-bit data,
followed by a
termination
character
Data to be encoded.
The error correction or size selection determines the symbol size and other characteristics of the
symbol, as shown in the following table. Attempting to encode more data that has been made
available will result in no symbol printed.
