In keeping with the trend of covering high-volume inkjet all-in-one (AIO), or multifunction printers this month, here’s a review of the Epson WorkForce Pro WP-4590, a $500-list workhorse that delivers excellent print quality, print speeds, and a low cost per page, or CPP. While this AIO has been around a little while, and therefore not as resplendent with all the latest features as some competing models, it has one of the lowest per-page operational costs in the business. If you print thousands of pages each month, you can’t really go wrong with this printer.
