Not in the true virtual sense, or background printing, I don't think.
The closest I came was to create a large virtual screen, do my
printing to the real screen and save the screen to the appropriate
part of the larger "screen" in memory. Easyptr has the WSAIN, WSASV,
WSARS, L_WSA and S_WSA extensions to handle save and restore areas.
There were some extensions which allowed a degree of background
writing to windows, though I never used them (PICE or PEX or something
like that, can't remember from memory).
Not exactly what you wanted though, sorry.

Subject: [ql-users] Virtual Screens
It would seem to be an advantage in pointer programs to be able to
create a virtual screen area, which one uses all the normal printing
and graphics routines and copies back the appropiate section to the
window everytime something is changed or the size of the window is
changed.
So
open #3 virtual_screen
print #3 "hellow World
copy virtual_screen window
etc.
Has anybody done any work on this?
