Abstract
A double-sided printing device for paper handling is proposed by the invention to allow users to print on both sides of a sheet of paper. The double-sided printing device employs the interaction between the switches, the obstructing unit and the turning unit to allow a sheet of paper to enter the turning unit and be turned over so that its back side will be directed to the printing unit.
