Very slow print time on scanned or bitmapped images.

A. This is an inherent problem on a PostScript printer. To optimize the
output speed, limit the amount of information that is sent to the printer
to what is optimal for it. Sending more information will only result in
the printer spending time discarding data that it cannot utilize. Perform
the following:
1. Limit colors to 8-bit (256 or indexed) rather than 24-bit color.
Most image editing applications utilize 24-bit color selection
when selecting an RGB or CMY/CMYK color choice.
a. If using PhotoShop, at the Menu Bar, click on MODE, and
select INDEXED COLOR. The default values (Resolution: 8
bits/pixel, Palette = Adaptive, and Dither = Diffusion) are
the values to accept. Click on the button: OK.
b. If using a scanner to input the image, there usually is an
8-bit selection. This may help, although it usually is
better to scan the image in with better selection settings
and let the software application perform the conversion.
c. For other applications, consult your software manual or
contact your software manufacturer.
2. For photographic or halftone images, limit the dpi value to 150
dpi or less.
