Rated 3 out of 5 by J Burlington from Incredibly Expensive I can't believe how expensive the toner is! It's doubled in price over the years. I love the printer, but feel captive to these prices. $226.99 is exorbitant - even with a discount I can't believe the price!

Rated 5 out of 5 by satschild from Dependable Performance Although the toner is pricey, I get 10,000 perfect copies from each toner cartridge. I have tried the "reconstituted" toners, but have been nervous that I wouldn't get the kind of copies I need and rely on for my business. So for peace of mind, I reorder the "real" toner and take advantage of promotions offered by HP.
