Ok say you want a 6" diameter circle and are printing at 300dpi.
Create an circle 6 x 300 = 1800 pixels diameter.

That's only because you are printing at 72 ppi. You need to understand the
difference between ppi and dpi, Suggest you start with Wayne Fulton's site.

>>>Create an circle 6 x 300 = 1800 pixels diameter.

That only works if the image resolution is the same as the printing
resolution.
