Printer vs Screen Res.
<<Being that the Epson is a 720×720 dpi printer, what is the best image size to
use (in pixels)
My experience with the Color stylus is that reletivly small files can look
good.
for example a 800×1200 file could be indistinguishable from a 1600×2400 file
and print much quicker.
If you have problems centering the image in photoshop you might try printing
from coreldraw where precice image placement is possible.
