Printing Speed Versus Color
The BJC-7000 Series Printer Driver for Windows can interpret and translate the
full spectrum of colors, up to 16.7 million colors. When printing in color, there is
a significant increase in the amount of information that the driver has to interpret
and translate. When printing black ink only, the driver has only one color to
interpret.
By decreasing the amount of colors that the printer driver has to interpret, you can
significantly decrease the time needed to translate the information. This will speed
up the overall printing process.
Ways to Improve Print Speed in Windows
To improve printing speed, you can try the following:
o
Turn off the Print Manager in the Windows Control Panel (Windows 3.1
only).
This avoids the extra step of sending the print file to the Print Manager
and may increase your printing speed by as much as 25%, depending on
the computer you are using.
o
Add a permanent swap file in Windows 3.1.
Under the 386 Enhanced icon in the Windows Control Panel, add or create
a permanent swap file that is from 4 MB to 9 MB. The computer will be
able to prepare the print file faster. See your Windows documentation for
instructions.
o
Avoid diffusion halftones.
In the Quality tab, choose Diffusion for Halftoning only when printing
final output or photographic images. Choosing a Halftoning setting of
Fine/Fast allows documents to print as much as 20% faster because the
computer does not need to compute to "best possible position" for each
dot.
o
Avoid color adjustment.
In the Color tab, disable the Color Adjustment option. This feature takes
longer to process in the computer because it requires special information.
