Using bit image graphics, you can draw almost any kind of illustration
with your printer.
Bit image graphics mode enables your printer to draw almost any kind
of illustration by printing a dot at any location on the page. Your IBM-
compatible MICROLINE will work properly with any graphics software
package designed for the IBM Personal Computer and IBM Graphics
Printer. No software modification is required; images will be printed
without distortion.
If you have IBM DOS you can use a software package (or BASIC
commands such as CIRCLE, LINE, and DRAW) to create an image on
the display screen (your software or BASIC manual will explain how),
then dump it on to the page via the Prt Sc command key on your
computer. The next section, Screen Dumps, gives some examples.
The section called Programming Bit Image Graphics explains what you
need to know in order to write your own graphics programs in BASIC
without using the screen dump method.
Screen Dumps
This feature lets you print a reproduction of any image on your display
screen. Simply press the SHIFT key and the Prt Sc key at the same time;
whatever is on the screen will be printed on the page.
