Increasing the Print Speed
Just as printing at a high resolution requires more processing
time, printing in color takes longer than printing in black and
white because the volume of data in a color document is much
greater. For this reason, it is important to be selective in your
use of color if you also require a faster print speed.
Even if your document requires the highest resolution
and extensive use of color, for example when printing a
camera-ready composite that includes color photographs, it
may still be possible to optimize the print speed by adjusting
other printing conditions. Keep in mind that changing some
conditions to increase the print speed may also lower print
quality.
The following table shows the factors that inversely affect print
speed and print quality (increasing one will decrease the other).
