Define Downloaded Bit Image
Enters a downloaded bit image (such as a logo) into RAM with the number of dots
specified by n1 and n2. It 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.
A downloaded bit image and user-defined characters cannot be defined at the same time.
