I have wiped a toner cartridge with a paper towel and chucked thst sucker back into a ye olde HP from 20 years ago with a broken guider clip and it still prints perfectly fine.

I wiped it because it was leaving a smudge at the edge of the paper after never cleaning the rollers for aforementioned 20 years.

I guess I can add briefcase printer for mission impossible as a use case for inkjet lol
