Bit Image Mode, Single Density (Normal Speed)
ASCII Code ESC K n1 n2
Hex Code 1B 4B n1 n2
Dec Code 27 75 n1 n2
Purpose Selects single (normal) density bit image graphics.
where
n1 + 256 n2 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)
Discussion This code prints specified data as bit image graphics at normal
density, 60 dots per inch horizontally and 72 dots per inch
vertically. For more information, see “Bit Image Graphics” on
page 201.
Example The following example produces a pattern of Single Density Bit
Image graphics. The 9-byte bit pattern is repeated 27 times.
Compare this example to the double density and quadruple
density examples.
