Advances made by Epson in various print head technologies have been realised in the Epson Stylus Pro 9450 with an incredible line accuracy of up to +/- 0.01 per cent per metre, even on tracing paper and plain paper. This tenfold improvement on earlier models makes the Stylus Pro 9450 a perfect solution for most CAD and GIS applications where nothing short of industry-leading accuracy is critical.
