2D Barcodes
The EPIC 3000 supports a number of 2D and Stacked barcodes. The terms stacked
barcode or multi-row barcode code are more accurately applied to those barcodes
made up of a series of one-dimensional barcodes. The term Matrix code generally
applies to 2-D codes that code the data based on the position of black spots within a
matrix. Each black element is the same dimension and it is the position of the element
that encodes the data.
Note: When printing 2D barcodes HRI (Human Readable Information) is
generally not used. The EPIC 3000 Supports HRI when printing 2D
barcodes but makes no attempt to align the text with the barcode.
Note: Space between the barcode and any HRI if active is controlled by
the printer. If HRI is not active, the same white spacing is used. It is up to
the user to enforce a quite zone between the barcode and any user data.
Code 49
Code 49 barcode is a stacked barcode containing between 2 and 8 rows, each
separated by a separator bar. Each row contains 16 "words" or character pairs with a
start and stop character. The last row also contains the number of rows in the barcode.
There are 2400 possible words which can be generated from each pair of characters.
Symbols with less than 7 rows contain 2 check digits in the final row. Symbols with 7 or 8
rows contain 3 check digits in the final row.
Function
ASCII
Hexadecimal 1BH 62H <14> {information} [NUL]
Decimal
Note: There is no user control of the number of rows or columns.
Note: The scale may be set from 2 to 6
Note: GS-1 encoding may be activated for both Code16. There is an
FNC1 indicator in the barcode that indicated 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.
