This reads like fiction.

> I opened my preferred internet faxing service. This is a tool that allows me to send a fax purely through digital data. It would cost $20, exactly the amount someone had donated to the blog last week, but if I didn't do this, I would lose all my benifits. It costs me zero paper. It costs me zero toner.

> ...

> For the recipient, a fax is a physical reality. It requires paper. It requires ink. It requires time.

I doubt it it would actually happen that way. My guess is there's a very high chance that the recipient is also using some kind of internet faxing service. So no actual paper was harmed by this prank.

> Two hours later, my phone rang...

> "Sir, please. You have to stop the fax. It’s… it’s been printing for an hour. It’s jamming the machine. We’re out of toner."

Oh yeah. Total fiction. Can't you stop a real fax machine by hanging up the phone? They work with dial-up. I wouldn't be surprised if there's also a "cancel print" button.
