Printer settings in Mac> 32
Pages
Choose whether to print all the pages of your document or just a
section of it.
Paper Source
Selects the paper tray to use for your print job.
Quality
Selects the print resolution.
The High Quality (Multilevel) setting produces the best graphic
images but it can take longer to print.
Photo Enhance
Use Photo Enhance to significantly improve quality when printing
images. The printer driver analyses any photographic images and
processes them to improve the overall appearance. This setting
cannot be used together with the "High Quality (Multilevel)" print
quality setting.
Toner Saving
Toner saving uses less toner when printing your document. This
is best suited to draft text documents as it lightens the print
significantly.
