(First of all, I selected 2 business day delivery .. ordered late Friday afternoon and it was here Monday morning). Installation for dummies (my words) CD walks you through in minutes. Minimal interaction on the user's part when installing by CD, once the usb cable is connected, it does the rest (sets the time, date, etc according to your computer info) love that! I had read the negative reviews but purchased anyway because most did not pertain to me. I just needed a basic printer/scanner/copier and it does these things wonderfully. Yes, it is a little louder than most, but not to an annoying level, and yes it is a little slow, but again it isn't as slow as others I've owned. If you're printing manuals, etc this is probably not the printer for you, but for everyday personal and home office (printing invoices, email correspondence, other documents) scanning and copying, then I highly recommend it. Thanks again, HP for amazingly fast shipping!!
