Laser printers are the preferred option for people who value speed because they are much faster than most printers that use ink cartridges. The electromagnetic process that takes place inside a laser printer is highly precise and allows it to run large print jobs quickly and efficiently.
The inkjet printers are generally slower because the jets that control ink output are not as precise as laser printer technology. Inkjet printers also tend to hold fewer sheets of paper which means more breaks to refill. While some inkjets are marketed as having laser-quality print speed, they are usually not capable of the speed provided by a high-end laser printer. This isn't to say that they are better overall, of course. Inkjet printers have their own advantages that laser printers do not.
So, when it comes to printing speed, laser printers take the lead.
