Graphics
This selection specifies how graphics are sent to the printer.
The options available are:
Vector This option allows you to send graphics to the printer as a
mixture of vector and raster images. Vector graphics typically
print more quickly than rasterized graphics.
Vector graphics are composed of distinct shapes (lines, circles,
ellipses, and boxes) that can be scaled and edited
independently. Vector graphics do not become distorted when
they are resized.
Raster This option sends graphics to the printer as bitmap images.
Bitmaps typically print more slowly than vector images and
become distorted when scaled.
Resolution
The resolution setting affects the amount of detail that is
reproduced on graphic images. Graphics resolution is
measured in dots per inch (dpi). Therefore, a 600 dpi setting
renders images using 600 dots (pixels) per every inch of the
image.
The image quality of printed documents typically increases
with higher resolution (dpi) and bits per pixel settings, but it
often results in slower print speed and increased toner
consumption.
600 dpi The images will be printed using 600 x 600 dots per inch (dpi).
Use this option if quality is more important than speed.
300 dpi The images will be printed using 300 x 300 dots per inch (dpi).
Use this option for text only jobs or where speed is more
important than quality.
