Printing text box with hidden text

I'm looking for some help with a problem I'm having with a "drawing
tools" text box. I have a form that contains a text box. The problem
is when a user types into the text box and exceeds the box, they can
continue to enter text past what appears on the displayed box. When
the form is printed out, what ever was not displayed on screen is
truncated.
So, is it possible to limit the text box to be locked from scrolling?
Or, is there a way to get Excel to print the entire contents of the
text box?

Thanks for any help on this quirky problem.

Anyone else experience this problem?
