An inkjet printer has to be used at least monthly if not more often. If you left it plugged in, the printer was likely squirting ink in to a waste tank to prevent the nozzles from drying out and ruining the printer.

Laser toner can sit unused without drying out (it's dry powder already).

Oh that's interesting. Yes that is exactly what it did! Didn't think that'd use so much ink though!
