Re: Lexmark next
The difference being that when it comes to printers, most of the complicated bits are in the handle.
Not strictly true - many inkjets have the print head in the cartridge (not that I'd ever advocate using an inkjet). Monochrome laser printers usually have the imaging drum as part of the toner cartridge, and colour ones as a separate consumable. The only 'complicated' bit is the laser, which these days is a mass produced £0.0001 laser diode, and the control electronics, the most advanced bit of which is probably the voltage switching power supply.
