I ordered this printer on the Thursday night and it arrived 12:30 on the Saturday so well done to Amazon for that. When it arrived I unpacked it and plugged it into my laptop with a USB cable ( not supplied ) and ran the setup from the CD. It all went well and the printer was printing about 10-15 minutes after it arrived. Setting up the wifi was not so easy but it wasn't rocket science either. You have to plug the printer into your router directly using a network cable ( supplied ) then find out what the IP address of the printer is buy going into the router configuration page. Once you have the IP you use a web browser to browse to the address where you get the printer menu. Setting up the wifi after that was a simple case of entering the name of the router and the wap key. Next run the CD on your computer again but this time install for a network printer, this is a clear option on the setup menu of the CD.
Printing is easy and fast and although the photo quality isn't the best its not bad for a laser and its very fast, 30 seconds for the page to be done. The quality of colour documents is fantastic, very crisp and sharp with solid text and colour. Amazingly it also looks like you get full set of toners as I have printed 20 or 30 full A4 photo's and countless number of documents yet the toner report its still got 95% capacity left.
All in all I am very happy with the Samsung CLP-315W. Its easy to use, has fast printing and is a very nice looking machine. I got this printer because I was sick of every time I wanted to print something with my old inkjet I had to clean the heads and on some occasions I had to replace perfectly good ink cartridges because they had dried up. Also the WIFI allows me to stick this printer in a cupboard somewhere out of the way. I have my own laptop, my daughters laptop and my son's PC all connected via the WIFI and it all just works with no drama and no wires.
For the price I would highly recommend this printer.
