Just got a magazine in my hand.
There is a test on six printers; five best:
Epson Stylus Photo R1900 (G, L, 2),
Epson Stylus Photo R2880 (G, H, 4),
Epson Stylus Photo R3880 (A2, T, 5),
Canon Pixma Pro9000 Mark II (1)
Canon Pixma Pro9500 Mark II (G, 3)
The R3880 prints A2, the others A3+ according to mag.
(A2 = ~600×400, A3=~400x300mm, divide by 25 for approx. inches).
All judged “good and almost equal prints” after creating your own color profile (e.g. “Colormunki” required, add almost $1000?).
Numbers indicate pricing, 1 < $1000, 5 > $1500 (in SWEDEN).
T=Top class lowest cost. L=Low cost, G=Good buy, H=high cost.
