Here's the reply I got from AACOMAS today:
"Thank you for your email. No, there is no option to preview the application before printing. The web page itself is essentially the preview, because that is exactly what is printed. If we can be of any further assistance, please let us know."
My question is, if the web page is exactly what is printed, how are they able to print pages that allow them to read the personal statements and other pieces of information that do not appear on the screen but require the scroll bar?
