Yes there is a reason: To print high-quality photos. I have an ink jet for photos (admittedly rarely needed these days) and a black&white laser for everything else. Also, part of the problem is that lot of people don't realize how expensive it is to run an ink jet and how massively cheaper a laser is in the long run. The average person needing a printing goes to the store and sees a laser for around $200 and an ink jet for $49, and buys the ink jet, thinking it's a better deal.
