Epson rates the Workforce Pro WP-4545DTWF at 26ppm in black and 24ppm in colour. Although we didn't see anything like these speeds under test, the printer did manage 10.7ppm on our 5-page text print and this rose to 12.6ppm on the 20-page test. Less than half the rated speed, but still more than reasonable for an inkjet all-in-one.
Better still, the machine's duplex performance, at 8.5spm, is considerably better than from most other ink-jets, largely because there is virtually no pause between page sides, to allow for ink drying. This is the bane of most rival machines, such as the Lexmark OfficeEdge Pro 4000, which only managed 5.4spm.
The 5-page text and graphics print produced 5.6ppm, which is again a lot lower than the claim, but quite good against the competition. A single-page colour copy took a reasonable 28s and a five-page black text copy from the ADF came through in a lazy 53s. A 10-side duplex copy took 1:46, which is good for an inkjet machine.
A 15 x 10cm photo stormed through in 35s, but despite our best efforts, we couldn’t get Epson’s iPrint, its Android print utility, to direct its output to the rear tray, the only one suitable for feeding photo paper. Although it spotted the Workforce Pro WP-4545DTWF, it doesn’t cater for paper type, size or tray selection.
Text quality is generally good, with characters formed better than from some cheaper Epson machines and with less ink spread. Draft print is faint, but still readable and obviously saves quite a bit of ink. Colour print is bright and fills are solid, with no signs of dithering. Our test photos showed natural colours, though by default dark areas were too dark.
There are L, XL and XXL ink cartridges to choose from, with Big Ben, The Eiffel Tower and Pyramids on them for identification. Using Pyramid cartridges, which are good for laser-like print runs of 3,400 page each, page costs come out at 1.8p for a black page and 4.8p for colour. These are both excellent and mean you won’t be paying over the odds for consumables in this machine.
Although the SRP for the Epson Workforce Pro WP-4545DTWF is £350, it’s available online for around £190. At this price is has to be a bargain. As well as colour laser speed, good quality prints and very low running costs, it has wireless connection, easy control from its touchscreen and offers three different paper sources. This is another versatile and cost-effective small office all-in-one from Epson.
