There is a method of reducing the actual number of data bytes sent to the printer when using the
~DG
 command.
If the HEX string ends in an even number of zeros (0’s), a single comma (,) can be substituted for ALL of the zeros. If the HEX string ends in an odd number of zeros, one zero and a single comma is required. The exclamation mark (!) and the colon (:) described under Repeat Values can also be used.
The text rows in your editor may not be the same as the dot rows used by ZPL II. The editor may word wrap or truncate the dot rows. ZPL II ignores the end of a text line (carriage returns and line feed characters).
