EXIT
Leaves the graphics mode and returns the printer to normal
operation.
The parameters for these commands are entered as ASCII strings.
For example, to send the value 100 to the printer in graphics mode, you
use LPRINT “100” instead of LPRINT CHR$(lOO). The difference is
that three codes (1, 0, and 0) are sent to the printer instead of just one
(ASCII 100). To see the difference, study the example programs that
follow.
