A printer includes a main body, a bracket, a lifting mechanism, and a paper tray. The main body is capable of printing and outputting paper. The bracket is attached to the main body. The lifting mechanism is secured to the bracket and includes a retaining plate. The retaining plate is moveable between a first position, where a first distance is defined between the retaining plate and the bracket, and a second position, where a second distance is defined between the retaining plate and the bracket and is less than the first distance. The paper tray is configured for receiving the paper. The retaining plate is moved from the second position to the first position when the paper tray is inserted into the bracket, and moved from the first position to the second position when the paper tray is released.
