[Description]
Define a downloaded bit image using the number of dots specified by x and y
x specifies the number of dots in the horizontal direction.
y specifies the number of dots in the vertical direction.
d specifies the data of bit map.
[Notes]
The number of dots in the horizontal direction is x× 8, in the vertical direction it is y× 8.
If x× y is out of the specified range, this command is disabled.
The d indicates bit-image data. Data (d) specifies a bit printed to 1 and not printed to 0.
The downloaded bit image definition is cleared when:
ESC @ is executed.
ESC & is executed.
FS q is executed.
2-D bar code is executed.
Printer is reset or the power is turned off.
The following figure shows the relationship between the downloaded bit image and the printed
data.
