Increase Text Area Field

Great plugin! However is there a way to have the Text Area field be four lines deep as a standard? When entering notes in the last field here (http://tulsaholistichealth.com/test) and printing, only the first two lines show up on the print out. Any lines below as the field expands while typing do not show up. The client needs four lines as a standard.
Thanks!
