The IOU can be printed or handwritten, but the signature must be handwritten.
It is not necessary to press fingerprints, but it is a stronger proof. You can borrow as much or as little as you like,
and there is no fixed format for IOUs. It is enough to clearly state the loan amount, repayment time, borrowing location, borrower and other things related to the loan and repayment on the IOU.
If you are borrowing money, whether there is interest and the amount of interest must be clearly stated.
