4.4 How to obtain

nl

and

n2

In the MX-82 Printer, you have to send the amount of data by

nr

+

n2

in hexadecimal

numbers following the ESC K or ESC L. If the amount of bit image data is 300, then

nt

and

nz

may be derived as follows;

nl

= (Amount of data) MOD 256

= 300 MOD 256

=

<44>D

=

<2c>H

n2

=

INT (Amount of data/256)

= INT (300/256)

=<l>D

-<ol>H

You can also use Appendix 4, code Table, to find the corresponding hexadecimal

numbers to the decimal numbers. The schematic of data transfer sequence in the

Bit Image mode is shown in Fig. 64.
