Bit Image Programming Format
The Bit Image command format is:
ESC CC(n1)(n2)DATA where:
ESC = the Proprinter compatible header
CC = K, L, ,Y or Z to select dot density
(K=single, L=double, Y=single, Z=double)
n1, n2 = n1+ 256(n2) defines the number of data bytes
DATA = the dot pattern bytes
Refer to the following guidelines when using the Bit Image Programming
Format:
•The syntax of the bit image expression must be correct.
•The expression must include the appropriate dot density control code,
the number of bytes of data to be plotted, and the data itself.
•The number of data bytes and the n1, n2 definition must be equal.
•Any characters following n1 and n2 will be interpreted and plotted as
data until the n1, n2 definition is satisfied.
•If n1 = n2 = 0, then control codes K, L, Y, or Z are ignored:
n2 = 2(700/256) = 700
bytes of data; 2 sets of 256 with a 188 remainder
n1 = 188 = 188–byte remainder
The program statement is: ESC K(188)(2)(DATA)
NOTE: Depending on the host computer system, it may be necessary to
include a width statement within the BASIC program.
•The maximum number of data bytes in the DATA portion of the
program statement (when using 132–column paper) varies according to
the operating mode:
At 60 dpi, Single Density = 792 bytes
Double Density = 1584 bytes
•Data in excess of the right margin is discarded. If the auto line feed is
enabled, data in excess of the right margin causes a Line Feed (LF) and
continue printing on the next line.
