After calling myself having thoroughly researched various all-in-ones prior to purchasing, I narrowed it down to this and it's sister Pro 5500 model. Since it appears the specifications are identical with the exception of the 5500 having a touch screen, I chose the Pro 4000. I tried it out for a few weeks, but couldn't get past the problem of the unit not being able to stay connected to WiFi even though the signal strength showed as excellent (being placed 3 feet or less away from the router). It was a pain to get reconnected when it should never have disconnected in the first place. I'm not sure if it was caused by the printer going into standby/sleep mode, or why this constantly happened. Probably would have been worse had it been further away from the router where I had planned to eventually place it. Every time, in order to get it to reconnect to WiFi I had to connect a USB cable, and it just got to be too much for it to be a so-called wireless printer. There's a big difference between sleeping and dying. Had I wanted a wired printer, I would not have chosen this model. I would consider it in the future were it not for that very annoying problem.
