The e310dw isn't a high-end printer, and it shows. Computer Shopper says its text is "average for a low-cost laser," with graphics coming out worse. However, About feels the quality is roughly what "you’d expect from a monochrome printer." Speeds were also middle of the pack, though About says they're actually "quite good for printer this small and inexpensive."
The e310dw might be fairly middlebrow at basic printer functions, but Dell squeezed in a few extra features that manage to lift it above the pack. Duplex printing is certainly a nice surprise, and PC Mag says you'll appreciate the "useful convenience" of being able to print from your phone.
It's small and unassuming, but the e310dw can still pack a bit of a punch -- especially considering what you'll pay for it.
