Subject: Screen Dumps 

Although best known for its task-switching features, BackGrounder ii
(BGii) includes a screendump capability -- to file or printer.  It captures
ascii, but not graphics, characters when the hot-key/command is
pressed, then restores the cursor and screen to its original state.
This feature requires a screendriver.  Drivers are included for
both types of Kaypros ('83 and '84), Wyse 50, TVI, Heath/Zenith 19,
and a number of other terminals, as well as info on writing a new
driver.

For Kaypros, there are at least 2 roms that contain the low-level
primitives for dumping the screen to a character device.  The TurboRom
is one; I forget the name of another.  Dumping to a file requires
bdos-re-entrancy and therefore something like BGii.
