mode (180 dpi), which can
give output a jagged look.

Solution
Use only print media

Print Media" on page 2-35.
Many types of paper have a
"correct" side for printing.
If your paper does, make
sure that side is facing up.
If the paper has no obvious
correct side, try turning the
paper over and printing on
the other side.
