We use DocuSign extensively to sign our contracts. No need to print out, ink sign, then scan back in — all done with secure electronic signature.
If you do print out and ink sign, you can take a picture with your phone and send it to us. We accept that as the signed contract. No scanner necessary.
Lastly, most modern office printers double as scanners and often as fax machines. Or you can scan and directly email.
Lots of ways around it without having a fax machine.
