Excellent printer

This printer is great. I have used ink jets and they break all the time. Laser jet is the way to go Especially if you run your own business.

Does Exactly What I Wanted

I researched a bunch to discover a printer for not only basic needs but one that could print on my 7 x 10 note card stock quickly and without misfeeds. Even on heavy stock the printer was excellent, it paused once in a while to cool down but printed one after another quickly. I am impressed! It runs quiet too. Wish I had invested in this a long time ago. The Smart Install didn't take but got it installed first try with the disc provided. Thank you HP your machine saved the day.

A Great, Color Workhorse Nearing End of Its Life

This was my second purchase of this printer. My first was may a year earlier and is functioning well right beside this new printer. My needs suggested a second, color printer with duplexing, and I had no qualms about getting a second of these HP451dn's. I've liked my experience with the first during the prior year. It seems to be conservative with toner use, tho there are 4 toner cartridges to maintain. Replace them all with HP toner & you've paid more than the price of the printer. But I use color very selectively, so the trail color cartridges that came with my first HP451 are all still in use 15 months later. The downsides of this printer is that (1) it allows 256mb add-on memory to flush out its memory to 384mb; the major manufacturers as well as HP no longer offer this module so you have to scrounge for it at relatively high prices; (2) the printer is not the fastest printer by any means; (3) HP's documentation quality is bifurcated: either VERY detailed & sophisticated, or sorely lacking. You'll have to scratch around if you have any need for the PCL commands.

Love it every bit as much as my old HP.

I am particularly happy with the two-sided printing which I expect to be using frequently. I never had that before and it is amazingly fast. The extra cost for that feature will be more than made up in the savings on paper and the speed with which it produces the finished product.

Excellent Color Laser

This product replaced the same model which had heavy use but finally gave out. The old model was about 6 years old. One complaint for the new model is when I put the HP 305A black ink cartridge from the old model into the new one, it would not authenticate. All the other colors from the old were put into the new and they authenticated. Second complaint is the new model is taking a long time to print once I click on print from my computer. It also stops during printing as if it's spooling again. This didn't happen with the old model until I stopped working.
