Is it possible to eliminate the notification and only have a responder emailed?
We have a contribution form that if the person wants to fill out on line, then hit submit so it sends them a pdf so they can mail in the contribution if they don’t want to do an online payment.

Yes. You may delete the notification/autoreponder as per your requirement from the form settings. Please refer to the guide below:

If you want the use to make an offline payment, you may display the information to send the check or bank account information on the form based on the selection. Please refer to the guide below that can help you with setting a payment form with other option.
