Most government agencies don’t use ink type printers. It is too slow.
What do they use?
Laser printers use ink
Heck, I stopped using inkjets about 7 years ago. No need for color and whatever pictures my wife has printed at W-Mart, doesn't come close to the cost of printing them with colored ink and special paper.
If I were to throw out a laser printer when the toner ran out, I would still be printing cheaper than if I used a ink printer.
