Connecting through Wi-Fi also means you can take advantage of Epson's host of free mobile printing apps that let you print directly from mobile devices. First, the Epson iPrint application for iOS and Android devices enables you to print Web pages, photos, documents, and anything else on a smartphone directly to the WorkForce 645, though I did notice some of our photos got inadvertently cropped from time to time. I wouldn't recommend printing important images like business presentations this way; it's more appropriate for quick outputs of spreadsheets and to-do lists.
Epson also launched its Connect Email Print app at the same time it announced the 645. Connect Email Print lets you send a print job directly to a unique e-mail address assigned to every WorkForce 645 printer. This means you can attach anything to an e-mail and send it to the printer's e-mail address, and the print job will be waiting for you in the output tray when you arrive home. Anyone can use the e-mail address, and I can imagine it could come in handy for remote workers hoping to share information with the home office.
The Epson WorkForce 645 printer ships with four separate ink cartridges for cyan, magenta, yellow, and black. I used Epson's XL black and color cartridges that cost $20 and $17 to factor the most cost-efficient price per page, an based on Epson's posted ink cartridge yields, the cost of printing is refreshingly affordable at only 2.5 cents per page of black ink and 3.2 cents per color.
I'm equally pleased with the 645's effort to push the speed of Epson inkjet printers. The WorkForce dominated four of the competitive printers in all but the photo speed test, where it fell behind at 1.12 snapshots per minute, so I wouldn't recommend it if quick speeds are a high priority. But for all other jobs, the chart below illustrates the WorkForce 645's capable performance.

I'm confident recommending the WorkForce 645's output for professional documents like slide shows, spreadsheets, and handouts. The internal driver settings let you choose between Photo or Best Photo mode, but keep in mind that you'll wait longer for the finished product with Best Photo. Text quality offers a similar choice between simple Text and a more complex Text and Image mode. Subtle differences between the two are noticeable using a magnifying glass, but not nearly enough in the snapshot photos and graphics documents to warrant the extra ink.
Nevertheless, I'm satisfied with the printer's color reproduction and text character formation, but many of the color blends in the snapshot photos are marred by color blocks and an undersaturated haze. Bright colors in prints don't pop as boldly as they should, but that's usually the case with business-oriented printers.
