5 out of 5 eggsDependable - Very good on toner use

Pros: When it was time for a new printer, I decided to upgrade from inkjet to laser (type I used to use). I had used HP laser jet series in the past and decided after some research, that HP still was my choice. At first I bought a series 200 LaserJet and found that it just could not hold up to the demand for home and occasional business use. I went to a nearby office supply store to allow me to "look & play" with the LaserJet 400 M451dn. I decided to "upgrade" from the LaserJet 200 series to the LaserJet Pro 400 M451dn, so back to Newegg for the purchase. Ever since I made the switch, the M451dn has performed flawlessly and never let me down, in grand HP style. The color and black is sharp and even, no streaks or disappointments (even with long legal sized documents). If I had it to do again, I'd buy this same printer. Holds up well to home and small office applications and work loads. It's easy on toner use too. I always use HP toner - why take the chance? It's not the cost of the printer as much as it's availability when you need it RIGHT NOW!!!!

Cons: No Cons, for this printer, as far as I'm concerned.

Other Thoughts: Connectability is ideal, as it works with USB & ethernet. I print from my MacPro, iPad, and iPhone all the time, whether I'm within WiFi range or not. The double-sided print function also saves paper for those long documents.

3 out of 5 eggsCheap printer with negatives

Pros: Low price. Duplexes.

Cons: Toner cartridge capacity pretty low. Doesn’t know, when the toner is really out, like me previous HP printer. Doesn’t play so well with OS X. Illustrator and Acrobat can’t print from the multi-purpose tray.

5 out of 5 eggs

Pros: USB connection, and network connection. All the colors of ink come out in a nice tray. My wife likes the white color. And of course, the print quality is excellent. OH... and to my surprise, this thing can print on both sides of the paper at the same time. Epic printer!

Cons: It doesn't cook me breakfast, but it does motivate my wife to do so.

4 out of 5 eggsLove this printer

Pros: Color, envelope handling, HP Eprint, Good for Small Office/Home Office

Cons: slow to print first page, toner cost

Other Thoughts: I bought this printer to replace an Oki C530dn that I'd had for over a year. The Oki had color matching issues and envelope handling problems that I couldn't solve. This is a relatively new model of printer for HP, so there wasn't a track record, but I've always had pretty good luck with the higher end HP products.
I needed this printer to print our company's letterhead, envelopes and business cards with acceptably high quality in the same color I see on the screen. I'm very happy with the color matching I'm getting from the HP LJPro 400. My Oki wrinkled the envelopes when I printed the return address on them; the HP handles this task flawlessly. In fact one of our partners thought I was getting them printed by an offset printer.
HP Eprint software comes with the printer, and I have used that successfully to print while out of town. It's also compatible with Apple's IPad and IPhone, so my husband is able to print from his Apple devices.
It comes with the small toner cartridges installed, so after printing ~800 sheets, I'm down to 60% capacity in the color cartridges and 40% capacity for the black cartridge. I'll replace these as they used up with the larger capacity cartridges. Since it's not my default printer, I'm hoping to get a year out of each cartridge. So far I'm on track. It will cost in the neighborhood of $400 to replace all four toners.
