I just received my new Epson 545 and found the wireless setup to be breeze. My previous no-name "wireless" printer just never connected to my home network.
After the brief and clear installation guide I was AirPrinting from my iPhone and iPad. I've very impressed with the control panel and especially the ease of replacing the ink cartridges, due to the top loading.
You can send a fax out from the laptop thur the 545 put you can not receive faxes to your laptop you can only print it up. This is not very good when you are in a wheelchair and canot get to the fax machine to get the faxes until somebody gets it for you because the wheelchair will not go thur the doorway.
The workforce 445 is a well designed machine. It went together seamlessly During installation with the easy to understand instructions. It recognized my Wi-Fi network immediately and shook hands like old friends. My three desktops and iPad Joined the team without a stumble.
