If you print more than the average person, you may want to consider ditching traditional ink printers for a laser printer at home. Laser printers have a few advantages over inkjet printers, the biggest of which is speed. Because there’s no ink to dry, laser printers generally print much faster. They also tend to be more cost effective, with toner cartridges costing more than ink cartridges up front, but printing more pages, although I’ve generally found ink tank printers even more economical if that’s your main concern.
