eSign PDF / Guide
You do not need to scan your pen signature. You can draw it on the screen. Or take one photo of it and use it again and again.
Short answer
You can draw your signature on the screen with your finger. You do not need a printer or a scanner. If you want your real pen signature, take one photo of it and use that. The iPhone's built-in tool can add a drawn signature. eSign PDF does both and saves it for next time, with no account, for $59.99 one-time (US).

A signature added with the iPhone's built-in tool sits on top of the page. Some Windows computers and Android phones do not show it. The other person sees an empty line.
eSign PDF locks the signature into the page (this is called flattening). Then it shows up on any computer or phone.
Your iPhone's built-in Markup tool lets you draw a signature. Open the PDF, tap the pen icon, tap +, then Add Signature. For a simple one-page form, that can be enough. It does not let you use a photo of your pen signature. More help: how to sign a PDF on iPhone.
