A bit image is structured by a collection of dots arranged in rows and columns. A collection
of eight dots sequentially arranged in a column is called a pattern byte. The smallest unit
of the bit image is called a pattern element. There are two types of patterns that are
determined by the number of dots used in an element: 8-dot and 9-dot elements.

Note:
(n1) and (n2) specify the number (k) of bytes of graphics data to follow, where
k = 256n2 + n1.
p1 p2...pk specifies graphics data.
In 9-Dot Image mode, the printer needs twice the number of bytes per column
of data. Therefore, the number of bytes included in the command is twice the
number specified by (n1) and (n2).
