Canonís Pixma MG6650 impressed
us so much that it secured itself our A-List seal of approval when we
reviewed it recently, so the pricier Pixma MG7550 has a tough act to
Whatís the difference between them? Physically, not a lot. The MG7550
shares its stablemateís no-frills design and chunky, black plastic
chassis. Indeed, itís almost identical to the MG6650 save for a few
tasteful touches, including a slightly more compact chassis and the use
of glossy plastics rather than a matte finish.
The MG7550 also has a slightly larger and more responsive touchscreen
than its cheaper peer, making navigating the options and establishing
Wi-Fi connections very easy.
Take a quick glance at the specifications and youíd be forgiven for not
seeing anything of note. Look closer, however, and youíll see that the
main difference is the MG7750ís more refined, six-tank ink engine, which
adds grey to the five-ink roster of the MG6650.
The top resolution is higher, too, at 9,600 x 2,400dpi compared with
4,800 x 1,200dpi, and you also get a higher-spec scanner, with a maximum
optical scanning resolution of 2,400 x 4,800ppi versus the MG6650ís
1,200 x 2,400ppi.
Canon makes a lot of noise about the MG7550ís photo-printing
capabilities and, upon printing a 6x4 inch photo and A4-sized colour
image, itís clear those boasts arenít without basis. The MG6650 is an
excellent photo printer, producing warm colours and natural skin tones,
but the MG7550 beats it soundly.
Rich, saturated colours and sharp details abound here, but we were
really taken with the startling lack of graininess. In blocks of colour,
such as skin and blue skies, the MG7550ís extra resolution really pays
dividends. And despite the extra quality, thereís little difference in
speed, with the MG7550 delivering 6 x 4in prints at best quality in 50
seconds each, and the MG6650 jetting out the same file in 52 seconds.
The MG7550ís scanning and copying speeds were good, too. It processed
our 6 x 4in 600ppi photo in 16 seconds and copied the same image in 53
seconds, while copies of our A4 mono and colour ISO documents were
delivered in 16 and 25 seconds respectively. As expected, the quality of
the photo suffered a little in the copy, the print exhibiting some grain
and colours appearing slightly washed out, but image quality was sharper
than we were anticipating, and we didnít notice any of the smeariness
weíre used to seeing on copied photo prints.
Standard document printing saw the MG7550 perform at an almost-identical
clip to the MG6650: mono and colour documents output at a rate of
13.9ppm and 10.1ppm respectively, with the MG6650 printing at 13.3ppm
Running costs are also similar for documents, but a touch more expensive
for photo printing, thanks to the extra grey ink. To keep running costs
as low as possible, weíd recommend investing in XL ink tanks, rather
than the superficially cheaper standard tanks, since youíll make more of
a saving in the long run. We calculated the running costs at 2.4p for
mono prints and 8.1p for colour; using standard tanks would almost
double the price at 4p and 17p.
In terms of the physical connections, the printers are once again very
similar: the MG7550 shares the MG6650ís USB 2, 802.11n Wi-Fi and card
reader, as well as the Pixma Printing Solutions app, which allows for
wireless printing from an Android or iOS device. Unlike the MG6650,
however, the also MG7550 has a 10/100 Ethernet port for wired networking.
In all, the Canon Pixma MG7550 is a fantastic printer for those with a
serious recreational interest in photography. It delivers superb-quality
photo prints at a reasonable cost, and itís pretty quick too. However,
itís much more expensive than the MG6650, so if youíre not bothered by
what is, at the end of the day, a very small difference in quality,
youíd be better served by the MG6650.
