Expanding textarea on key down

Hi,

Ive got a situation whereby i need to be able to print the contents of a form out. The problem arises that there are textarea fields on the form. If the user has input so much information that it is only all viewable by scrolling to the bottom of the textarea then this part would not show up when printed.

The only way i can see round this is when a key is pressed within the textarea element, javascript needs to check whether there are more rows of text than the default value of rows....if so then the script needs to add another row each time this occurs.

Does anyone know how this can be done as i cant even find a script that detects how many rows a textarea element has???

Thanks in advance
