n1 + 256n2) defines the number of data bytes to follow.
DATA = ASCII characters for the dot pattern bytes.
NOTE: The DATA can be expressed in a format with the appropriate decimal
values of the ASCII characters supplied, especially in cases where
the dot patterns of nonprintable characters are required.

“DATA” consist of 8-bit dot columns, with the MSB at the top,
and “1” bits producing dots. For more information, refer to

Chapter 8, “Graphics.”
Comment
This mode is similar to ESC L, except that four dot columns are
printed in the space normally taken by two columns. You can
change graphics density with the ESC ? command.

change graphics density with the ESC ? command.
Example
The following example produces quadruple density graphics of
the pattern used in the standard density example. The amount of
data must be quadrupled for quadruple density (the data are
used 108 times rather than 27).
