Abstract
A printing apparatus has a desk-top printer housing having a paper input port, a paper output port and a data input port. A digital processor is disposed in the housing and is operatively connected to the data input port. The processor is programmed to detect odd pages and even pages in an electronically encoded document arriving via the data input port and to separate odd pages of the document from even pages thereof. A paper moving engine including rollers is disposed in the housing for moving a paper sheet through the printer housing from the paper input port to the paper output port along a predetermined path. A first laser printing assembly is disposed in the housing along one side of the path for printing an odd-numbered page of the document along one side of the paper sheet. A second laser printing assembly is disposed in the housing along an opposite side of the path for printing an even-numbered page of the document along an opposite side of the paper sheet. The processor is operatively connected to the laser printing assemblies for controlling the first laser printing assembly to print the odd-numbered page of the document along the one side of the paper sheet and for con…
