Need urgent help with Certification of Finances form.

So there is this form of financial aid that we internationals have to fill: http://www.depauw.edu/files/resources/2017-18-certification-of-finances.pdf
Do we have to send in a hard copy or will a PDF copy do? I am asking because it says on page 2 “signature of bank official”.That cant be done online(as far as i know) so I am confused.
Any one who has sent it, how did you do it?

You will print the forms.

Signatures must be original signatures. Signature of back official must be an original signature (and will probably be stamped by the bank along with the actual original bank statement. You most likely will not be able to send these on line. You will print the form, fill it out, obtain the signatures and mail the information to the school.
