When you see the gadgets today, the general consensus would be that the form factor has improved, and the functionality has been augmented. At present, many devices have become portable which in turn has made them a lot more versatile. Epson too has been at it, and it can be clearly seen in Epson WorkForce WF 100 which is among the best Epson inkjet printers today. This inkjet printer comes with a built-in battery, and is compatible both with Wi-Fi and Wi-Fi Direct.
If you are someone who really does not have much time on your plate, and need to print a great deal, the Epson WorkForce WF 100 may be the right business printer for you (if you run a business). You can easily pack it in a bag and carry it along, and print plenty of documents directly from your Smartphone or laptop without needing power sockets or cables!
