Horizontal Dot Columns)
*The number of bytes sent is represented by the following formula:
n = 8 x n1 x n2 (n1 x n2 must be less than or equal to 4608).
Enters a downloaded bit image (such as a logo) into RAM or Flash with
the number of dots specified by n1 and n2 in A756 Emulation, unless
loaded into Flash. The downloaded bit image is available until power
is turned off, another bit image is defined, or either Initialize Printer
(1B 40), or Define User-Defined Character Set (1B 26), command is
received.
Note: This is only available in A758 Native Mode. If multiple logos
are to be defined and used, this command should be preceded by the
Select Current Logo Command to define the number by which this
downloaded logo is to be referenced.
By default, A756 Emulation loads downloaded bit image to SRAM,
while A758 Native Mode loads them to Flash.
See the illustration on the following page for a graphic representation
of the downloaded bit image.
