The Epson Epson Stylus Photo R230 delivers outstanding photo quality with its 5760 Optimized dpi (using RPM technology) and a new Multi Layer Piezo (MLP) print head. The print head is capable of printing a minimum droplet size of 3pl with Variable Sized Droplet Technology (VSDT). This incredibly high level of precision produces smooth gradation of colours and tones, while reducing the graininess that commonly occurs in photo printing.
