Hi there,

Feel free to blabber away, this is really good information, for example I didn't
know that 200 dpi was sufficient for the Epson printers, I had heard said that
there was no quality increase above 500 dpi, but 200 dpi means that I can get
much larger prints from my 600 dpi scanner.

Thanks for the tip

Glenn
