The initial setup was far more complex than I've experienced with Epson or other devices. Since my device did not include any paperwork, I had to locate the operation manual online. Calls to the seller, BeachAudio only resulted in them referring me to the manufacturer for assistance. They also assumed I wanted a refund, when all I needed was some technical assistance. As for the device itself, it is a powerful machine that does everything a small business or family could need. It's fast and quiet. I appreciate the wireless functionality as I do not need to tether it to my desktop. Envelopes are fed through the front panel which opens up. For those needing to print large amounts, I believe an accessory tray is available. This device only comes with one tray which can support various paper sizes, although we have it setup for standard copy paper.
