Reassign image mode
Esc? cm
Ÿ
This command enables you to redefine the horizontal resolution attached to a particular image
mode. Hence, you could assign a density of 90 dots per inch to the image mode normally
associated with 60 dots per inch, which is selected with the Esc K command. All subsequent
Esc K commands would then generate images with a horizontal density of 90 dots per inch.
Ÿ
c is the character which signifies the graphics mode: K = single-density (60 dpi), L = double-
density (120 dpi), Y = double-speed, double-density (120 dpi) and Z = quadruple-density (240
dpi).
Ÿ
m defines the new horizontal resolution to be assigned to the specified graphics mode. m must
be in the range 0 to 7. A value of 0 selects 60 dots per inch, 1 and 2 select 120 dots per inch, 3
selects 240 dots per inch, 4 selects 80 dots per inch, 5 selects 72 dots per inch 6 selects 90
dots per inch and 7 selects 144 dots per inch.

a defines the horizontal density of the image. Set a to 0 for a horizontal density of 60 dots per
inch, and to 1 for an approximate horizontal density of 120 dots per inch.
Ÿ
The image consists of 256*n
column of 1/8".
Ÿ
Each pair of bytes represents a vertical column of nine dots, the most significant bit of the first
byte representing the dot at the top of the column, the least significant bit of the first byte
representing the second dot from the bottom, and the MSB of the second byte representing the
dot at the bottom of the column. Bits 1 to 7 of the second byte are not used. 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.
Ÿ
Images are printed from left to right.
Ÿ
Images are printed at a horizontal resolution of 60 or approximately 120 dots per inch, and at
an approximate vertical resolution of 72 dots per inch.
