*There are n1 x n2 x 8 data columns (the value [d]). The value n1 x n2 x 8 does not appear in the data stream.

The bit image data is represented by d. The number of dots is:

•n1 x 8 in the horizontal direction

•n2 x 8 in the vertical direction

The downloaded bit image remains in effect until:

•A different downloaded bit image is defined.

•The printer is initialized, reset, or turned off.

•A user-defined character set is defined.

A user-defined character set and a downloaded bit image cannot be defined simultaneously. When the Define Downloaded Bit Image command (1D 2A) is performed, the user-defined character set is cleared.

The relationship between the bit image data and the defined dots is shown below.
