Epson rates the Workforce Pro WP-4535DWF at 26ppm for black print and 24ppm for colour and these figures are as silly as on previous Epson models. However, our real-world test showed a black speed of over 10ppm even on a short, 5-page document and up to 12.8p on a longer, 20-page one. More than this, a 20-side document printed as 10 duplex pages returned 8.5 sides per minute, far and away the fastest duplex speed we've seen on a sub-£200 printer.
A single page colour copy took a surprisingly long 28s, but a five-page black copy from the ADF completed in 52s and a 10-side duplex copy still took only 1:46. These are all, again, very good speeds.
We've always had provisos in reviews of Epson small business inkjets when it comes to print quality, but the new engine in these Workforce Pro machines shows that it is possible to get clean, well-reproduced text from a piezoelectric printhead.
The documents we printed were very good and this extended to the graphics in our colour test document. Even the colour photocopy produce good results, with little colour fade. Finally, a full-colour photo on Epson glossy paper produced an excellent image, more than good enough for any business use.
There are three different cartridge yields available on this machine: the standard capacity Big Ben set, the high-capacity Eiffel Tower set and the very high capacity Pyramid set. Using the Pyramid cartridges gives a page cost for a black page of 1.8p with colour costing 5.0p, both including 0.7p for paper. These are very low costs, way below those from a laser or LED printer and very competitive with something like HP’s Officejet Pro 8000 Enterprise A811a.
Epson’s Workforce Pro WP-4535DWF is something of a bargain. For under £200 you get a colour multifunction printer which can genuinely print at over 10ppm, or 8.5 sides per minute duplex, can produce full duplex copies, includes fax and can print a full-colour photo much better than any laser. With its highest yield cartridges, it can also print up to 3,400 pages between changes and at a cost of under two pence per black page. What’s not to like?
