The total column number is calculated by n1+n2 ×

256 for 8-pin graphics and

 

 

 

 

(n1+n2× 256) x 3 for 24-pin graphics.

 

 

 

 

 

 

 

 

Each bit data in the 8-pin graphics corresponds to 2 print pins of the print head.

 

 

 

 

The following figure shows one column of data and its corresponding print position.
