Reset the printer.

EC%ØB

Enter HP-GL/2 mode.

IN;

Initialize HP-GL/2 mode.

 

 

SP1;

Select pen number 1 (black).

 

 

SC-3000,3000, -2000,2000,1;

Specify scaling mode, making P1

 

equal to (-3000,-2000) user-units

 

and P2 equal to (3000,2000)

 

user-units. Isotropic scaling is

 

specified.

 

 

PA-1700,2000; CI750,45;

Specify absolute plotting and

 

move to (-1700,2000), the center

 

of the circle to be drawn. Draw

 

a circle with a radius of 750

 

user-units and a chord angle

 

of 45°.

 

 

PA300,2000; CI750,30;

Specify absolute plotting and

 

move to (300,2000) to draw

 

another circle. Draw this circle

 

with a radius of 750 user-units

 

and a chord angle of 30°.
