Super Product

I was suprised by this product; it really works well and it's easy to use all of the different featues. It's saved me a fair bit of money so far and I've not had any trouble with it. Will be upgrading my other printers to this model soon!

I have been using HP printers in my business for many years but this one lets me down continuously. It was bought to provide duplex and booklet printing but there are paper jams almost every time these functions are used and I have now given up trying.
