Data is printed in 24 dots bit image of resolution of 203 x 203DP.
z
Print total dots divided by 256, quotient is n2 and remainder is n1.
z
Total dots in bit image mode are n1 + (256 x n2).
z
If the bit image input data exceeds 1 dot/line (432 dots) position, the exceeded data
will be disregarded and it is not automatically printed in the next line.
z
Bit image data (Dn) interprets bit 1 as print and bit 0 as not print.
z
The total dots to be printed in the bit image must be the same with quantity of bit
image data that corresponds to the dots. If quantity of bit image data is less than
the total dots, the same amount of following data, same as the balance, is treated
as bit image data. If it is more than the total dots, the same exceeding volume of bit
image data will be treated as normal data.
z
When bit image is continuously printed, print by lines (3mm) and stop is repeated
for such reason as communication speed and others, the print density may not be
consistent. Use NV bit image to solve the problem.
