<< Details >>
This command is effective only if this command is entered
at the start position of a line in the standard mode.d refers
to bitmap image data. The bit for the dot to be printed is
„1“ and the bit for the dot not to be printed is „0“.The
required number of image data per line is as follows
depending on the number of heating elements in the head:
dots of heating element 192 dots 288 dots 384 dots 576 dots
No. data per line 24 bytes 36 bytes 48 bytes 72 bytes
<< Function >>
Specifies the raster bitmap image specified with
(nL + nH x 256) lines in the vertical direction.
