Considering the width of A3 paper is only 1.4 times greater than A4, the
Stylus Photo R1800 really makes its presence felt. It's a very
substantial machine with a huge, telescopic paper support at the back and
a counter-balanced output tray that swings out from the front. You can
adjust the paper guides for any paper size from 15cm x 10cm prints,
through A4 and A3, to A3+, which measures 19 x 13 inches and enables
borderless A3 prints.
