5 out of 5 eggsGreat Printer

Pros: Affordable, print quality, build quality, built in web server, ethernet and wireless

Cons: Price, Photo Quality, No Duplexer

Other Thoughts: If you want photo quality at it's best, stick to inkjet. In my case I print very rarely, so an inkjet is inconvenient, since it dries up if not used very often. For the odd picture I may want to print I can head to the store and have it printed for 30 cents. That being said, I was blown away by the quality of prints from a laser at this price. I got it on sale for under $300 and didn't expect the print quality of a $2000 laser.

If you have a high quality high resolution photo the output can be quite good and framable. I'm talking a photo from a digital SLR camera with a good lense. And that's on plain paper. Remanufactured cartridges are common for this model so the print cost is very reasonable. There is a built in web server on the printer so installing drivers is easy as they are stored on board the printer. I used the ethernet connection and it works great. There is no duplexer but one is available on an upgraded model so that doesn't bother me. I love that it has a paper tray compared to an inkjet so your paper is stored and stays straight and good. With an inkjet your paper is exposed to the elements and everytime you go for a sheet of paper it's curled. I wish this printer had a 500 sheet capacity so a ream would fit, but no other printer offers that option either so it's no big loss.

Honestly, if you don't need the 100% print quality of an inkjet, I would not recommend an inkjet printer. I would settle for a laser that has 80% the photo quality of an inkjet, but twice the quality when printing everything else. You'll never need expensive coated photo papers again. You won't have to clean your print heads every once in a while to improve print quality. No more messing with ink and continuous ink systems trying to save money. A laser should last a long time compared to an inkjet so the long term investment is economical. Really, for 95% of the people who purchase inkjet printers, they should actually be purchasing a color laser printer, and I feel in this price range the HP 400 series is the best.

I found a high resolution 10MB or so photo of a tiger on the internet and tested it out on plain paper. From a couple of feet away my family couldn't tell the difference between it and an inkjet. But with low quality pictures you definitely notice. For printing documents and web pages, office documents, .pdf's, etc... it's in a league of it's own that an inkjet can't compete in.

Compared to other sub $300 color laser, Samsung, Brother, Xerox, and other brands arn't as good when it comes to print quality and build quality. Also support for remanufactured cartridges is great with the HP. This printer gets the 2 thumbs up.

1 out of 5 eggsWhat a piece of junk!

Pros: it's huge and takes up lots of desk space

Cons: Driver installation failed several times, called HP so they could give me an even older driver and its still failing. Told to replace USB cable and try another port, then told to try another pc, all with the same problems.

Other Thoughts: If RMA wasnt going to cost so much I'd send it back

5 out of 5 eggsREVISED: DON'T >> DO BUY

Pros: I could not figure out how to edit my previous review so I am posting a new one.

As stated previously the specs indicate a good price/performance ratio, nice feature set. I thought it would be a good replacement for my pervious 10 year old HP printer. In the week or so that I have been using it I must say that it is performing well and living up to my expectations.

Cons: I my previous review I noted a problem that locked me out of the settings both on the front panel and the web interface. I became extremely frustrated after spending a few hours on 2 different chats with 2 different engineers and was told my only option was to send the printer back. Today I was about to contact NewEgg about a RMA but decide to try HP one more time. This time the support engineer's first suggestion was to rest the NVRAM, basically what I had been begging for and was told it could not be done. In short he gave me the simple procedure and 3 minutes later I was back into the printer. Everything is fine now. TIP: Even thought it does not mention it on the password page, DO NOT enter a password over 16 characters long or you will be locked out. Also if the tech support rep appears to be useless, politely hang up and try again because there are some who actually know what they are doing.

Other Thoughts: In fairness to HP just like the tech support reps an my company, they are not engineers and are working from knowledge base articles. HP: please include reset procedures in the manual. There is only one brief paragraph about restoring the factory settings, but this is through the menu which is locked out and useless. So update the docs and the knowledge base please.

1 out of 5 eggsDON'T BUY

Pros: Specs indicate a good price/performance ratio, nice feature set. I thought it would be a good replacement for my pervious 10 year old HP printer.

Cons: SERIOUS DESIGN FLAW: I set a password on the web interface. I wrote it down and am 100% sure that I have the password I entered but now I am completely locked out of the printer setup. I spent over an hour chatting with HP and apparently there is no way to factory reset and start again other than through the front panel menu. One catch the front panel menu is disabled when security is enabled. Only option, return to reseller. So use for 20 minutes then ship it back...

This is not acceptable. I'm going to Google around for a bit but to me it seems ridiculous that there is no way to reset the device when you have physical access. I already found one article where a teacher had one in his classroom and apparently a student entered a password, now he is locked out too. In the forum his only option was to send it back.

This is crazy.

Other Thoughts: By profession I am an embedded systems designer with over 36 years experience. We have and would never ship something that could not be at least "reset" in the field. I mean people forget passwords all the time. You should never be able to get past the password, but with physical access there should always be some way to factory reset the device.

They tell me they will replace mine under warranty, but they are telling me that everyone who forgets their password in a year is going to have to pay... This is more trouble for everyone.

This experience has definitely put me off HP printers. I have been using HP laser printers for decades, literally and had considered them the king of laser printers. Other companies have some nice offerings, but I stuck with HP out of loyalty. With this poor design, and the uselessness of the technical support, I think it is time to change.

Sorry for the rant, but I am quite frustrated.
