I believe there is an escape sequence that can be sent to the terminal
to do the same thing as pressing the "print screen" key. I didn't
want to complicate the original post by going into that. If your
program knows when to screen scrape, it can send the sequence at the
appropriate time. If the program doesn't know when to do it, and the
user has to press a key. Otherwise, how do you expect it to happen?
