Re: Motherf***ers. I strongly doubt this is the only HP that has done this.
Well Brother has the problem of some of their printers using proprietary languages. Which essentially means that after a couple of years they will become harder and harder to use.
However most monochrome laser printers have near infinite toner capacity, particularly old ones. So if you are looking for a monochrome laser printer, devices like the HP-LaserJet 4 series are kinda your best bet.
