"I bought a cheap laser printer instead. It's black and white, cost a few times more than one of those disposable inkjets, and has saved me quite a bit so far. As I understand, the toner in these guys doesn't go bad... it can settle in time, but if I take the toner cart out and shake it a bit, it's back to working again."
HP even lie about the toner. My LaserJet Pro 200 Color started complaining about low toner last year. I bought a new cartridge but decided to sit out installing it until something happened.
Well every so often it flashes the orange light with ever increasing cries of starvation. Bit of a nuisance having to push the <OK> key not once but twice to continue - especially if I'm printing from a remote location. I supposed that's HP's way of trying to bully me into givin' them dough.
No way! The copies continue to be printed perfectly from an 'empty' cartridge.
