Epson Stylus Color II Reference Manual page 44

Use a higher quality paper. For best print quality, use
EPSON special coated papers for 360 and 720 dpi or
EPSON high-quality glossy paper (720 dpi only).
Note:
Do not use high-quality glossy paper when you print at 360 dpi.
Make sure the Media Type setting matches the type of
paper or other media loaded in the printer.
If you're printing a scanned image and the colors are not
right, first try to fix the problem using your scanning
software program.
If print quality does not improve, see the following specific
problems.
Printed output is not what you expect or is faint or blurred.
You may not be printing on the correct side of the paper. Test
both sides to determine which side gives you the best print
quality. On coated paper, print only on the white coated side;
on glossy paper or transparencies, print only with the cut
corner facing the right side of the sheet feeder and remove each
sheet as it is printed to prevent smearing by the next sheet.
Check that the paper thickness and thickness adjustment levers
are set correctly for the media type. (See "Setting the Paper
Thickness and Adjustment Levers" in Chapter 1 for more
information.) Faint or blurred printouts can result if you print
on plain paper or labels with these levers in incorrect positions.
Use a higher quality paper. Also, check that the Media Type
setting in the driver is set for the type of paper or other media
you loaded. If you are using 720-dpi resolution, you get better
results when you use EPSON special coated paper for 720 dpi
or EPSON high-quality glossy paper.
