                The data contains image data that is n1 + n2 * 256 bytes. 

[Description] 

Specifies that an 8-dot standard-density bit image will be printed with the number of dot 

positions defined by n1 and n2. 

・

n1 and n2 indicate the number of dot positions. 

n1: The remainder from dividing the number of dot positions by 256 

n2: The quotient from dividing the number of dot positions by 256 

・

First, the data is lined up in one row as shown below. 

・

One dot of the image data is enlarged to 6 dots vertically by 6 dots horizontally. 

・

As a result, the image becomes 48 dots vertically × (n1 + n2 * 256) * 6 dots horizontally.
