Downloads and prints the bit imaged graphics. After printing a bit image, the printer
returns to normal data processing mode.

Values: Values:
a = bit image mode
1 = 8-bit single density
2 = 8-bit double density
m = the remainder of the number of dots in one horizontal line
n = the integer of the number of dots in one horizontal line
d
= the downloaded data bytes; set each bit to a 1 to print a dot or to a 0 not to
print a dot
Ranges: Ranges:
Hexadecimal: a = 00 or 01
m
= 00-FF
n = 00-01
d = 00-FF
Decimal:
a
= 0 or 1
m = 0-255
n = 0-1
d
= 0-255
Formulas
The number of data bytes is m + (256 x n ).
Related Information Related Information
If the bit-image data input exceeds the number of dots to be printed on a line, the excess
data is ignored. If
a, m
, or
n
are out of range, the following data is processed as normal
data.
For impact printers, the following table illustrates the location of each bit of the data byte
that is downloaded on the print head.
