Bests & Worsts Reviews from Amazon

I traded in a perfectly good HP All-in-One (circa 2001) for the convenience of wireless printing from a laptop. I've had the printer one month; am I sorry I bought the 4500 Wireless. Other than the wireless feature, I can't say anything positive about this device. It has frequent paper jams; the scanner turns white paper backgrounds into an ivory color background (making it difficult to paste scanned images like signatures into other documents with white backgrounds); it's very slow; black text often comes out gray, or worse yet, light green (!). This is about the worst printer I've ever purchased. I was a longtime HP supporter until I purchased this device. HP, you lost my loyalty.
