Hex Code
1B 4C
n1 n2 d1 d2...dk
Dec Code
27 76
n1 n2 d1 d2...dk
Purpose
Selects double density bit image graphics of 120 dpi
horizontally and 72 dpi vertically.
Expression
CHR$(27);“L”;CHR$(
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)
Comment
Double density printing reduces print speed.
Example
The following example produces double density bit-image
graphics of the pattern used in the standard density bit-image
mode example. The amount of data must be doubled for double
density (the data is used 54 times rather than 27).
