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 I BM Personal Computer and IBM
Graphics Printer. No software modification is required; images will be
printed without distortion.
If you have IBM DOS 2.0, 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 ex ­
plain how), then "dump" it onto 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 IBM Personal Computer 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.
