EN ES, Extra Space 23-51
ES, Extra Space
This command adjusts space between characters and lines of labels
without affecting character size.
ES width[,height;]
or
ES [;]
The printer interprets the parameters as follows:
z No Parameters— Defaults the spaces and lines between
characters to no extra space. Equivalent to (ES0,0).
z Width— Specifies an increase (positive number) or decrease
(negative number) in the space between characters. For
maximum legibility, do not specify more than one extra space
or subtract more than half a space.
z Height— Specifies an increase (positive number) or decrease
(negative number) in the space between lines. For maximum
legibility, do not specify more than two extra lines, or subtract
more than half a line.
An ES command remains in effect until another ES command is
executed, or until the printer is initialized or set to default conditions.
