Datamax DGL - Manual (Page 39)

39
UCC/EAN Code 128
DGL follows the UCC standards, and requires the amount of data that is
defined for the provided AI (Application Identifier). For example, with barcode
‘Q’ the required amount of data is 19 according to the Datamax manual. An AI
of ‘00’ requires 19 databytes, however, Datamax also prints the barcode when
19 databytes are provided with another AI. DGL does not; the amount of data
required is based only on the provided AI.
Barcodes Q, R, S and W1R all print the same UCC barcode on DGL (except
for differences in PDF placement); required lengths only depend on the
provided AI.

DGL does not accept more than 14 bytes as barcode data, while Datamax
does. However, according to the Datamax manual the maximum length is 14,
so problems are not expected.
PostNet
Datamax has a slightly larger width for the first space in the start character, all
other sizes match exactly.
MaxiCode
The postal code can have a length of up to 9 digits, and up to 6 for
alphanumeric on Datamax. DGL, however, always encodes using exactly 6 or
9. When less than 6 alphanumeric bytes are provided, trailing spaces will be
added, and trailing zeros will be added when the given data is numeric and
less than 9.
RSS14
The maximum accepted item number for RSS Limited barcodes is
1999999999999; DGL will not print the barcode when a larger number is
provided. Datamax does accept larger numbers.
DGL does not support X and Y Pixel-Undercut.
