Extremely disappointed with this printer. I'm an expert PC/network guy, so I had no problem hooking this up to work with my wireless network - some stuff worked great, such as scans over the network, OCR, and printing is fast. As others have said, it's incredibly noisy, although if it worked, I wouldn't care. duplex printing is great.
BUT my printer is now afflicted with the dreaded power-save problem that HP refuses to address. Yes, I've upgraded the firmware and the software - it just got WORSE. so now, to get the printer to work at all, I have to physically unplug it, plug it back in, and it works for 5~10 mins at best.
My next home printer will not be an HP. I find it ridiculous that HP is well aware of this issue had has not resolved it.
BTW - there's a lot of shill reviews on this site, from the "TOP contributors" : some of them are clearly cut-n-paste from each other! And please, people - don't write reviews if you "just bought this printer" - wait for 3 months and come back after you've dealt with the item for a while (and had to replace the inkjet cartridges for more money than you paid for the printer :-)
