How long does the laser toners last when out of the wrapping? -

I don t use the printer much.

They can last a long time. I have some LaserJet toner cartridges that are over 3 years old and still work. Sometimes I take the cartridge out and gently tilt it up and down to move the toner around that might have gotten stuck.

it will work for the next year or so. i think the ink will quagulate after a few years

Depends on humidity. I have known toners to last 5 years or more unwrapped.
