No decoration, no slogan, no clip-art of a fax machine. Just the fields. Fill them in on screen before downloading, or print blank and fill by hand -- either works.
Why would I use a blank cover sheet instead of a formatted one?
Sometimes you need to write on the form after printing, or the recipient's office requires you to fill in their own format. A blank template gives you the labeled structure without anything that gets in the way.
Can I print this blank and fill it in by hand?
Yes. The blank fields are rendered as underscore lines so the printed page is ready to write on.
Is there any difference in fax transmission between a simple and a fancy cover sheet?
No. Fax machines do not care about design. Simpler cover sheets with less ink may actually transmit slightly faster and produce cleaner output.
