[Code] <1B>H <2A>Hn1 n2
[Range] 1 ≤n1+ 256 ×n2 ≤378
[Outline] Thisc ommand allows printing in thebit imagemode. Divide the number of dots printed by
256 and assume its quot ient to be n2 and remainder to be n1. Therefore, the nu mber of
horizontal dots will be n1 + 2 56 ×n2.
If the bit image data is entered beyo nd the dot positions p rintable in one line, t he surplus data
will be discar ded. Normaldat a processing is re stored after bi t image printi ng. Printingis
done in a single direction.
