Re: Dpi settings
Well if DPI means Dots Per Inch, and you have an option of Dots Per Centimeter, of course you could do some conversions to change the DPC to your DPI.
If you want 300 DPI, you need to change that to DPC. Like so,
300 dots/in * (1in/2.2cm) = 136 + 36/99 dots/cm
Rinse and repeat for any other DPI you want.
