PPM (pages per minute) speed claims for lasers are close to the actual speed for printing simple text files at reasonably high quality. But for more complex images, such as intricate graphics, a slow printer engine with a fast processor can beat a fast printer engine with a slow processor.

If you take the claimed speeds for ink jets seriously, you'd have to conclude that most ink jets are as fast as or faster than most desktop lasers. They aren't. Claimed speeds for ink jets are based on draft modes you wouldn't want to use very often, and even for those draft modes, the claimed speeds are faster than you'll see in real-world use.
