Selects double density, double speed bit-image graphics of 120

where
(
n1 + 256n2) defines the number of data bytes to follow.
DATA = ASCII characters for the dot pattern bytes.
n1 = (Number of DATA bytes) - 256(n2)
(remainder of division of number of DATA bytes by 256,
sometimes referred to as MOD 256)
n2 = (Number of DATA bytes) / 256 (quotient of division)
n1 = (Number of DATA bytes) - 256(n2)
(remainder of division of number of DATA bytes by 256,
sometimes referred to as MOD 256)
n2 = (Number of DATA bytes) / 256 (quotient of division)
Discussion This mode prints double density with no adjacent dots. It is
similar to ESC L, except that if the graphics data contain
horizontally adjacent dots, the data may print incorrectly. This
feature is widely used to move the print head precisely, by
printing blank dot columns.

Example
The following example produces a double density, double speed
graphic image of the pattern used in the standard density
example. The amount of data must be doubled for double
density (the data are used 54 times rather than 27).
