Micro PDF 417
MicroPDF417 is two-dimensional (2D), multi-row barcode, derived from PDF417. Micro
PFD417 can encode up to 150 bytes. Micro-PDF417 is designed for applications
requiring improved area efficiency
The form of the command is as follows:
Function
Micro PDF 417
ASCII
[ESC] b <33><nL><nH><d
1
> … <d
n
>
Hexadecimal
1BH 62H <33><nL><nH><d
1
> … <d
n
>
Decimal
<27> <98> <33><nL><nH><d
1
> … <d
n
>
Where the data length is (nH * 256) + nL. The length is limited to be from 1 to 150
characters.

Note
: Micro PDF 417 shares a control table with PDF417. PDF417 allows
the columns to be set from 1 to 30, however Micro PDF417 only allows 1-
4. (0 will auto set the columns) If the columns are set out of range, it will
be limited to 4.
Note:
The encryption level cannot be changed for Micro PDF 417.
Note:
MicroPDF417 is used for composite barcodes which use GS1
formatting. When used for composit barcodes GS1 encoding is active.
Note:
The PDF417 and Micro PDF 417 specifications do not reference
GS-1 formatting; however GS-1 encoding may be activated for
MicroPDF417. There is no indicator in the barcode that indicates that GS1
is active. If GS-
1 formatting is used it’s up to the user to recognize that
GS1 is active and decode the barcode as GS1 data.
