You really should be e-filing the forms. Then you don't file any paperwork with the IRS, just print a copy to give to your payee.
I think you also misunderstand the "red" form. Read the instructions carefully here.

The red form you can download from the IRS is NOT to be submitted to the IRS. If you want to submit a paper form to the IRS, you have to order the official forms from the IRS or a business supply store, see for example

That's a form you run through a laser or inkjet printer, to make 6 copies. Copy A for the IRS is the approved IRS red ink version.
But just e-file instead.
