Canon rates the PIXMA MG6150 at 12.5ppm for black print and 9.3ppm for colour and these are much more realistic speeds than some of the company's rivals (Epson, are you listening?). Even so, we couldn't get more than 9.6ppm out of the machine printing black on our 20-page, long-document test, with 8.8ppm on the five-page test and 5.7ppm on the black text and colour graphics pages.
These speeds are actually pretty good when compared with many of the machine’s rivals, including those that claim much higher speeds for their machines. Where the Canon falls down, though, is in its duplex speed.
When printing on both sides of the paper, there are long pauses between sides for the dye-based ink to dry, and print is a lot greyer than from the pigmented black ink used on single-sided documents. Our 20-page test printed duplex on 10 sheets took 6mins 59secs, a speed of just 2.9 sides per minute.
A colour copy took 15 seconds and 15 x 10cm photo prints took between 40 and 56 seconds, depending on source. Actually, getting reliable timings from this machine is quite awkward, as it performs various ink housekeeping at random times during print, which can considerably increase the overall print time.
Print quality on single-sided black text pages is very good, with well-formed characters and no signs of any ink run. Fast mode print is nearly as good, though as mentioned, duplex print looks a bit faded in comparison. Colour graphics are bright and attention-grabbing and colour photos are some of the best we've seen from a consumer inkjet. Colours are particularly rich and full, while not looking over bright or exaggerated.
The six ink cartridges are all you have to consider as consumables and, although they're not particularly cheap, print costs come out at 4.1p for an ISO black page and 11.8p for ISO colour. These are on the high side against some of its competitors, though not unduly high, unless comparing with a Kodak machine.
This is a well-designed all-in-one with useful extras, such as direct CD/DVD print and duplex, though the slow speed of duplex print reduces its usefulness. Speed and print quality is much the same as from its predecessor, the PIXMA MP640, but that was already very good. The touch panel controls built into the scanner lid look a bit like a novelty, but are actually very easy to use and give the machine some extra sophistication.
