HP LaserJet 4P update + new toner cartridge

I finally got the 4P working perfectly, 2.5 years* after I got it. All it needed was a new toner cartridge. This video shows the first tests after installing the new cartridge. This was filmed last year, so it was only 1.5 years between getting the printer and getting a new cartridge for it. This is why you've actually seen the printer present in my room for the past year - I have been using it and it continues to work perfect.
