When you have a PDf file that has editable fields, the text that is entered into those fields will not be sent when you fax this type of PDF. If you want to send the text that you have entered with the PDF, you need to first convert the PDF (with the text you want entered into the editable fields) using this free website. Once you have a TIFF file, you can send that and the text you entered into the editable fields will be sent with the PDF.
