This reply makes absolutely no sense to me. Is there an easy way to wrap text in a field?

If you change the height of a text field like this:

Birger

I believe wrap when printing it out. It doesn't wrap it prints a long line of text. How do you wrap it when printing"

Is there any answer to this last question?  The text doesn't wrap in the print preview no mater what is showing on the screen as mentioned by Birger H.

Have you tried using a multi line text box instead?

So okay tested in with a normal text field.

here is my field on the form. You can see the text fills the field and the text is truncated.

In the print design edit mode - you  select the field and drag the handles so that it is wider in one or both directions

and here is the same field on the final print layout! (when viewed or printed )

Hope that helps
