Re: Motherf***ers. I strongly doubt this is the only HP that has done this.
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.
There was me thinking I'm quite the hipster with my HP Laserjet 4200dn with two toners and a spare fuser!
