The Epson WorkForce Pro WF-C5710DWF prints as fast and almost as cleanly as a laser model, but uses only a tenth of the energy and has lower printing costs. If you need a device with PCL 6 and PostScript emulation, go for the WF-C5790DWF, which costs 80 euros more and also comes with an XXL bag for 10,000 black and white pages.
