The problem
Someone sends you a PDF to sign. Your only option is to print it, sign with a pen, scan it, and email it back. That's four steps and a printer you probably don't have.
The fix
Upload the PDF here. Click where your signature goes. Draw it with your mouse or finger. Download the signed version. Skip the printer entirely.
