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.
