It churned out our six-page document in 1 minute, 11 seconds (5.1 ppm), almost double the 2.6-ppm average. The XP-640 spat out mixed text and graphics in a fraction of the time of most other tested models. The Canon TS6020 made two-sided prints at 3.5 ppm, while Canon's Pixma MG3620 did so at a pokey 1.7 ppm. The next-fastest competitor, the HP Envy 5540, clocked in at 3.6 ppm. But the XP-640 excelled here, making two-sided text prints at 5.5 ppm. The Epson has a duplexer, which isn't usually much cause for celebration in this budget class, as it can slow things down. For example, the Epson printed text documents at 9.1 pages per minute, versus the average of 8 ppm. On almost every timed test, the XP-640 was among the fastest inkjets we've tested. If the need for speed tops your list, the XP-640 is unlikely to disappoint. The only major missing feature is an automatic document feeder (ADF) for hands-free multipage copying. Other features include a duplexer for two-sided printing, Wi-Fi connectivity, and both a USB port and SD Card slot for printing from thumb drives and memory cards.
