“a”Counter specifies the number of data bytes following:
(counter byte) + 1 = (number of data bytes to follow) or
(counter byte) = (number of data bytes to follow) – 1
128 ≤ (counter byte) ≤ 255
“b”Counter specifies the number of times to repeat the next byte of data:
256 – (counter byte) + 1 = (number of times to repeat next byte)
(counter byte) = 257 – (number of times to repeat next byte)
Data which will exceed the right margin are discarded.
The vertical movement cannot be defined smaller than the current print density:
density must not be changed within Graphics Mode.
Avoid moving the print position upwards while in Graphics Mode.
This sequence is valid only in Graphics Mode ( ESC ( G, see page 67 ).
After printing raster graphics the actual print position is the most right dot + 1 dot
of the image.
Counter (a) and counter (b) can be mixed within the same sequence.
The dot count should be a multiple of 8. Otherwise the remaining data < 8 will be
discarded.
