Smoothing Jagged Outlines
This feature is unavailable when the XPS printer driver is used.
The Image Optimizer function reduces the jagged outlines that are produced when photos and graphics
are enlarged with your application. It allows you to print smooth outlines. This feature is especially useful
when printing low-resolution images from Web pages.
The procedure for performing Image Optimizer is as follows:
1. Open the printer driver setup window
2. Set image optimizer
Check the Image Optimizer check box on the Effects tab.
3. Complete the setup
Click OK.
The photos and graphics will be printed with jagged outlines smoothed.
Note
Depending on application software or resolution of image data, the image optimizer may have no
discernible effects.
It may take longer to complete printing when the image optimizer is used.
