We've yet to encounter a bad Epson scanner, and the unit fitted to the WP-4525 DNF is excellent. Captured documents were crisp, accurately exposed and faithful to the colours of the originals. Photo scans at 600dpi and above revealed a slight lack of focus, but contrast was preserved among the very darkest and very lightest shades. Images were unusually good for an office-orientated device, making this scanner suitable if needed for more than just low-resolution archiving. It's quite quick, previewing an A4 page in nine seconds and scanning it at 150dpi in 14 seconds.
Epson's TWAIN interface is the best we've used, although the one big omission is the lack of network scanning support at least using the pre-release drivers we had available. On the subject of omissions, there's no PCL or PostScript printing support, either, although Epson has said that this will follow.
Verdict
The Workforce Pro WP-4525 DNF achieves what it sets out to do: it's a competent MFP that, while it may not match an equivalent laser for durability, outright print speed or quality, comes acceptably close. At the same time it's smaller, quieter, cooler and less power-hungry than a laser, making it ideal for the smaller offices and workgroups it's aimed at. Its strongest card, however, is its running costs, which are far lower than any small workgroup laser we've seen.
Alongside products such as HP's Officejet 8000 Enterprise, the WP-4525 DNF makes a compelling argument for inkjets at this end of the market, but we can't help but wonder whether the technology is really ready for the higher-volume applications Epson apparently has in its sights. The bulk, noise and complexity of a laser is far less of an issue in large workgroup and departmental applications, where the technology's high power use is offset by the low cost of bulk printing. It'll take a special inkjet to compete here, but the WP-4525 DNF does suggest that Epson knows what it's doing.
