OKI claims print speed of 28ppm for this small printer and, although we only saw a maximum speed of 22ppm, this is still very fast compared with mono laser printers in its price range. The printer produced 18.7ppm on our standard five-page text print, but reached 22.2ppm on the 20-page test. Our text and graphics test produced a still healthy 17.6ppm and a 15 x 10cm photo took 21 seconds.
The printer has a duplexer built in and printing a two-sided, 10-page test took the speed down to 12.0ppm, but this is still a good result. Overall, speeds for this £150-ish machine, are well up the mono page printer field.
The quality of prints from the B410dn is good, too. Black text is sharp and well formed, with no sign of toner spatter, but a slightly light look to the characters. This isn't really a fault, but it does mean text can appear slightly grey. Business graphics are smooth, with good stipple patterns and very little unwanted variation in the greys.
Our test photo print, using the printer's highest resolution, reproduced well, with good gradated tints and plenty of detail in darker, shadowed areas of the image. However, given the comparatively high resolution of 2,400 x 600dpi, a dot pattern is surprisingly noticeable over the image.
There are two consumables needed to keep this OKI printer running: a toner cartridge and the drum unit. The toner cartridge needs replacing every 3,500 pages, but the drum unit should be good for 25,000 pages, so you may only need four during the whole life of the printer.
Using the cheapest prices we could find for both these components gives a cost per ISO page of 2.35p. This is on the high side, with most of the mono laser printers we've looked at recently hovering around the 2.0p mark.
Although the machine has a few shortcomings, most obviously a dodgy setup applet and a near unreadable LCD display, there are several bonuses which compensate. It's unusual to have a duplexer built into a page printer at this price and both duplex and single-sided print jobs are processed speedily and with little fuss.
Print quality is also above average and we don't think you'll be disappointed with any of the text or graphics output from this machine. Consumable costs are on the high side, compared with some of its competitors, but overall this is a solid, workaday home or small business mono printer, with the added simplicity of its LED imaging mechanism.
