NOTE
Changing
the resolution also changes the size of the printed raster
image.
At 300 dots/inch, each "1" sent to the printer represents
one dot; at lower resolution, however, each "1" represents a
number of dots. NOTE: Data is transferred to the printer as
either a "I" (dot) or "0" (no dot). For example, using 100
dots/inch resolution, each "1" sent to the printer causes 9 dots to
be printed. This is because the printer always prints 'it 300 x 300
(90,000)
dot/square inch image. In order to print at IQO dot/inch
resolution (10,000 dots/square inch), the printer forms a "dot"
from 9 dots (90,000/10,000 = 9). Therefore, your image printed
using 100
dots/inch resolution will be 9 times larger than the same
image
printed using 300 dots/inch. Likewise, the same image will
be 4 times larger (than
the 300 dpi image) using 150 dot/inch
resolution, and 16 times larger using 75 dot/inch resolution.
