If bits 1 and 2 of n
define rows 2 to 9 of the grid, the most significant bit representing the second dot, and the
least significant bit representing the ninth dot down. Simply set a bit to 1 to print a dot in that
position on the grid, or to 0 to print white space.

Downloaded characters are selected using the Esc I command and then printed by sending the
appropriate character codes.

The image consists of 256*n
of 4/30".
Ÿ
Images are printed left to right.
Ÿ
Images are printed at a horizontal resolution of 60 dots per inch and at an approximate
vertical resolution of 72 dots per inch.
Ÿ
Each byte represents a vertical column of eight dots, the most significant bit representing the
dot at the top. Simply set a bit to 1 if you want a dot to appear in that position, and to 0 if
you want white space to appear.
