How to select the portion of the text I want to print before I start scrolling? By shifting the red border that pops up on the page when I open FastStone Capture? But how exactly is this done?

When I press the ESC button the scrolling stops: that's ok, but when I print
I get a print of the whole text, including the sections beyond those that I want to print.

And before I start scrolling, should I choose To Word, To Editor, To File?

When scrolling is done, do I have to save the text somewhere before printing?

I have the latest version of FastStone Capture.

Many thanks in advance for your help and patience.
