Agreed. I have also never seen a fuser replaced with the toner/drum assembly.

Still, it's a good point being made here. There are some (rare) SOHO laser printers out there where the imaging drum is a separate part, and so the per-page costs go down because you're not paying for a new imaging drum every time you fill the toner. Our main workhorse printer at one of my old jobs was like that. Very cheap to run.

Those are pretty rare to find, though.
