Over the long haul, color laser is probably cheaper to operate. Brother makes a very good one. It stands up to the endless printing of a long lost descendant of Guttenberg. My print addicted spouse.
Another meaningless opinion.
We bought a Brother color laser last month. It was horrible and was returned after about three days.
DH got it to print his digital astrophotography images. I warned him that when I used both laser (Okidata) and inkjet (HP) at work, the laser’s colors weren’t true. He decided to try it anyhow. Colors weren’t true AT ALL. It streaked. Worst of all Brother’s customer service rep was rude and dreadful. But when it comes to cost of operating, the laser might be more cost efficient in the end.
(We’ve had good luck with Brother inkjets in the past.)
