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.
