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.

Any user-defined characters will be cleared from RAM when this command is used. See

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 1344).

Print Downloaded Bit Image

Prints the downloaded bit image in RAM at a density specified by m. It is ignored if any

data is available in the print buffer, if the downloaded bit image is undefined, or if the data

defined exceeds one line. A downloaded bit image and user-defined characters cannot be
