I have a Brother monocolor laser printer for which I buy the high yield toner cartridges which seem to last me forever.
I just replaced the cartridge and am trying to remember how I handled these previously. I seem to recall that HP included some sort of pre-paid return address label for recycling, but there's no such enclosure in the box.
For a while, a few years ago, there was some start-up franchise locally that was refilling cartridges. I seem to recall a chameleon or some-such critter in their ads...but I haven't run across any such ads lately. Perhaps they've gone defunct?
Anyhoo...what do y'all do with your empty laser toner cartdridges to keep them out of the landfill. Of course, in LBYM style, getting some cash in return would be nice.
