4.4 How to obtain n
1
and n
2
In the Type II Printer, you have send the number of data by n
1
+ n
2
in hexa-
decimal numbers following the ESK K or ESC L. If the number of bit image data is
300, then n
1
and n
2
may be derived as follows;
n
1
= (Number of data) MOD 256
= 300 MOD 256
= (44)
D
= < 2 C >
H
n
2
= INT (Number of data/256)
= INT (300/256)
= (1)
D
= < 0 1 >
H
You can also use Appendix 3, 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.
