RE: 1440 or 2880 dpi what exactly does this resolution represent?



Someone else on this list proved that everything that's sent to the Epson
printer driver is first converted to 720ppi, and then that is given to the
dithering algorithm which generates dots at whatever final resolution you've
selected. If you try to send it data at 1440 or 2880ppi, the detail will be
resampled at 720ppi, and will cause aliasing. Because of this, the
PostScript should be rendered at 720dpi for best results.
