 [Outline]    [The specification which is common to the model]  
• According to the number of dots specified in “n1”, “n2”, specify the bit image of mode “m”. 
• The number of dots printed is divided by 256, whose quotient is taken as n2 and residual as “n1”.  The total 
number of dots printed in the horizontal direction is equal to n1+(256×n2).
 
• When bit image data have been input in excess of dot positions that can be printed on one line, the excess 
data are discarded. 
• ”d” is bit image data. Bits to be printed are specified as “1” and those not as “0”. 
• The bit image modes specified by “m” are shown as follows:
