Wow... well yeah, those inkjet printers catridges are pretty expensive, and could have overtake the price of the printer itself when you keep buying it. I'm planning to buy a laser printer if my brother's doing heavy thesis work... He has to keep on changing catridges, when he got a huge load of his work printed.
Ahhh.. The LaserJet 4P. Those were the days. They have really improved laser printing these days. Even my budget-grade LaserJet 1020 prints faster and better.
