to have a jagged appearance. Higher resolution means smoother curves
and angles as well as a better match to traditional typeface designs.
Resolution values are represented by horizontal data and vertical data,
for example, 360 360 dpi. This printer can produce output with
resolutions up to 720 360 dpi precision.
