Calculation of the parameters for the BIM data

As the printer cannot recognize ANY command in the BIM data, before printing the

graphics, you must define exactly the number of BIM data items that will follow. The

graphic commands do this by means of two parameters, which can be calculated in the

same way for all resolutions.

These parameters,

n

2

and n1, are calculated as follows:

n2 =

whole number (number of BIM data items divided by 256)

n1 =

number of BIM data items-

(

n

2

x 256

)

In other words:

n1 is the remainder of the division of which the

q

uotient is n

2

.

Example:

To print a full line of graphic data in double resolution with an 80-column

p

rinter

,

960 b

y

tes must be sent after the command

ESC L

.

Parameters

n1

and

n2

are calculated as follows: n2

=

whole number of (960/256) = 3 n1 =

960 -

(

3 x 256

)

= 960 - 768 = 192
