In case you were in doubt, the S900 cannot be considered a general purpose printer. If you measure its times against those of desktop printers, it hardly compares with devices that are under $150 - it costs three times as much! There is one notable point, though: the S900 is very slow in black and white, but it is fairly fast in color. This implies that it has been optimized for this mode, which our photo tests confirmed.
A 10 x 15 cm photo printed in 4 minutes 40 seconds on the S800. The S900 is a lot faster, and only takes 94 seconds! It can even rival the fastest ones around, such as the brand new Canon S520 and S750, which replace the S500 and S630, respectively.
We also tested the S9000 in A3 border-free mode. Our test photo was printed out in less than eight minutes.
