Configuring The LQ-1600K Emulation With Control Codes
Graphics, Standard Density
ASCII Code ESC K
n1 n2 d1 d2...dk
Hex Code 1B 4B n1 n2 d1 d2...dk
Dec Code 27 75 n1 n2 d1 d2...dk
Purpose Selects normal density bit image graphics of 60 dpi horizontally
and 72 dpi vertically.
Expression CHR$(27);“K”;CHR$(
n1
);CHR$(
n2
);“
DATA
”
Where:
n1 = 0 through 255
n2 = 0 through 31
n1 + (256 x n2 ) defines the number of data bytes to follow.
d1 d2...dk = ASCII characters for the dot pattern bytes.
NOTE: d1 d2...dk (DATA ) consists of 8-bit dot columns, with the MSB at the
top and “1” bits producing dots. (0 < = d < = 255)
Example The following example produces a pattern of standard density
bit image graphics. The 9 data-bit pattern is repeated 27 times.
Compare this example to the double density and quadruple
density examples.
