[0002] A printer is one of the output devices of a computer, used to print the results of computer processing on relevant media. There are three indicators to measure the quality of a printer: print resolution, print speed and noise. When the printer is in use, the paper to be copied needs to be stacked and placed in the pull-out tray, and then the printer prints the stacked paper one by one;

[0003] Although the pull-out trays in some existing printers can limit the position of paper horizontally, they cannot limit paper piles of different heights, causing the paper piled on top to shift in position, which may cause paper damage or skewed printed patterns when the printer pulls the paper in. Utility Model Content
