z Paper Usage
This printer either has an optional duplexing accessory or one
already built in. The printer's duplexing feature, which provides for
two-sided printing, reduces paper usage and the resulting
demands on natural resources. Depending on the type of
software program in use, you can request for a number of pages
of your document to be printed on one page of paper. This N-up
printing practice and the printer's automatic/manual duplexing
feature, which provides two-sided printing, can reduce paper
usage and the resulting demands on natural resources.
