Canon makes more realistic claims than most for the speed of its printers and expects this machine to reach 11ppm for ISO black pages and 9.3ppm for ISO colour ones. Our five-page, black text document produced a speed of 7.32ppm, which only increased to 8.1ppm for the longer, 20-page test. A fast, draft mode print tipped in at 8.3ppm, not that far off the claimed speed.
Colour prints were also reasonable, with a five-page document giving 5.9ppm. Although they fall a little short of the claimed figures, they’re reasonable speeds from a comparatively low-cost printer.
Where the machine drops back is in duplex print, which is a standard feature. All inkjets have problems with drying times when printing on both sides of the paper, but Canon has one of the longest pauses between sides of any make we test. Here, it took 6mins 56secs to print the 20-page document as a 10-page duplex one, a speed of just 2.9 sides per minute.
A 15 x 10cm photo printed from a PC completed in a good 46s at best quality, though from a PictBridge camera, in normal mode, to took a less-impressive 57s.
Print quality from Canon printers is usually impressive, but here black text is a little more fuzzy than usual, showing some flow of ink along the grains of the paper. Colours are better defined and black text over coloured backgrounds is sharp and well registered. Solid colour fills are smooth with no signs of banding or dither patterns.
Photo prints are also well defined, with smooth gradations in skies, but darker areas are over dark and some detail is lost. Colours are natural, but there’s plenty of vibrancy, too, when needed.
The five print cartridges only come in one capacity, which makes page cost calculations simple, but gives no discount to people who are prepared to invest in higher capacity consumables. Using the best prices, we could find gives ISO page costs of 3.1p for black and 8.3p for colour. These are both better than average when compared with the printer’s main rivals.
If you don’t need the extra functions of an all-in-one printer, or want to spend money on print quality rather than print features, Canon’s PIXMA iP4580 is a good, workaday machine that produces excellent prints, quickly and at reasonable cost. There’s nothing much that’s new about the printer, but the mix was already pretty good.
