Printer Driver Functions (Macintosh)
(2) [Print Quality]
Move the slide bar to adjust the balance between print quality and speed. Moving the
bar to the right enhances print quality, and moving it to the left increases printing
speed.
(3) [Halftoning]
Select either [Dither] or [Diffusion] ink dot configurations.
(4) [Photo Optimizer PRO]
Optimises the colour of images taken from a digital camera or scanner. It is especially
effective for images affected by colour imbalance and over- or under exposure.
When printing several images on one printing page, optimisation is usually applied to
each image according to its requirements. However, if the image data has been
manipulated using cut and paste, rotation or other such operations, group optimisation
of all images on the page is recommended. In such cases, select the [Apply
Throughout Page] check box.
