HP OfficeJet Pro K850

Pros: large print-size capability...but that's all!

Cons: Noisy, expensive, glacier-slow, requires 8 costly cartriges

Summary: I bought this thing in an emergency situation, and I'm sorry I did...especially having just read that it doesn't work well with Macs. Guess what? It doesn't work very well with PCs either! I have both Mac & PC computers, and need a printer that works well with both platforms. This piece of garbage takes forever to do ANYTHING -- even the simplest of tasks. I sit and wait for at least 5 minutes for it to go through its repertoire of loud noises before it deigns to print a single page. And if you want multiple copies, make yourself a cup-o-coffe, 'cause you're in for a long wait! Oh yeah, don't even think of performing any other tasks on your computer while this thing is "working". And since all printers come with only low-capacity ink cartridges, I searched for the appropriate hi-capacity ones when ordering this printer online. So I ordered 4 printheads (at $34 apiece). Imagine my shock when I opened the box, and discovered that this machine requires not only printheads, but also 4 additional ink cartridges! WHAT?! And all of them (except the black ink) are dye-based! A huge disadvantage over my last HP printer (which had its own set of problems) that used archival Vivera inks (and only 4 cartriges, not 8!). And one last thing: the HP K850 is HUGE. I've never been so unhappy with a purchase in my life! If you have any inkling that this printer might be a good fit for you, do yourself a favor and research it thoroughly first!
