{k = n1 + FF(Hex) × n2

(m = 0, 1)

 

{k = (n1+ FF(Hex) × n2) × 3}

(m = 32, 33)

[Outline]

According to the number of dots specified in n1, n2, specify the bit image of mode n.

The No. of dots printed is divided by 256, whose quotient is taken as n2 nd residualas n1.

The total no. of dots printed in the bit image is equal to n1 + (256 x n2).

When bit image data have been input in excess of dot position of one line(448 dots) , the excess data are discarded.

d is bit image data, the bits subject to printing are taken as "1" and those not as "0".

The bit image modes specified by m are shown as follows:

[Caution]

When the values set in m (bit image mode) are out of the above range, the data

 

following after n1 is processed as normal printing data.

 

 

After completion of bit image printing, printer returns to normal data
