Purpose: Provides a way to print contents of a graphics screen
display.
Discussion
After using this command, pressing Shift + PrtSc (or calling for a
printout
using some application programs) prints the screen contents on the
printer in
graphics mode (printer must be capable of printing in graphics mode). If
the
display is currently in 320 by 200 color/graphics mode, and if you are
using a
graphics printer, the screen will be printed with up to four shades of
gray. If
the display is currently in 640 by 200 color/graphics mode, the screen
contents
will be printed sideways.
You can also print the contents of the screen from a program. Use the
following
coding:
PUSH BP
INT 5
POP BP
In graphics mode, printing will take considerably longer.
