[Default] The same as the internal character set.
[Notes] Horizontally adjacent dots cannot be printed.
l
Only the top bit is valid in the secondary data bytes in the ver-
l
tical direction.

[Example] 7 X 9 font
l
When the dot pattern for code 20H is defined as shown above.

[Description] Sets the bit image mode using m and the number of dots using
n1
and
Divide the number of dots to be printed by 256. The integer
l
answer is n2 and the remainder is n1 . Therefore, the number of
dots in the horizontal direction is calculated as : n1 + 256 X n2.
• If the bit image data input exceeds the number of dots to be
printed on a line, the excess data is ignored.
"d" indicates the bit image data. Set a corresponding bit to 1 to
l
print a dot, otherwise set it to 0.
