Sorry this can't be done. One option would be to make your Multi-line Text Field bigger by dragging the bottom right corner and you can also limit the number of chars to make sure you see all content in printed PDF form... but i know this is not always possible as you might be expecting a lot of text.
Is there an easy way to determine the character count that is visible in a given multi-line text field when designing the form, so if I want to allow 500 characters, the text box I create is large enough for 500 characters? Obviously I can just do a trial and error process using a cut and paste of 500 characters and testing it, but is there an easier way?
The maximum char count will depend on the font family and size used. We do not support finding that 'magic' number automatically. Your trial and error solution is probably your best approach.
