After the Deli thermal printer is installed, there will be a shortcut icon DeliUtilityTool on the desktop. This is the printer setup tool. Double-click to open it, and there is a [Set Printer] in it. Click the second line on the left to open, and there is an option to set the [Start Automatic Positioning] point, and then select Close. In this way, the paper is changed when the printer is turned off, and the paper will not move when it is turned on after the change. Change the paper to a better position, or it's useless to print it out.
