Printing crisp images of pics taken with Olympus C-4000

Helllo!

I bought one of these great cameras months ago, but, never had the time to sit and figure it all out. I have a great printer (Epson C-82, and photoshop, etc., however, even when shooting images as tiffs (hi-res, too), and printing out, I still see pixellation around the edges! How can I print images that are smooth like regular photographs? Is it a preset in the printer window I need to change up? PLEASE HELP!!!!

Thanks,

Greg
and yoiu can e-mail me back at:
ggould@point360.com

use photopaper
and before printing, go to settings and change all of those to maximize the quality

or read the printer's manual
it should describe the process pretty clear
