How to set A4, plain paper when printing on computer?

Let's take opening a word document as an example. We want to print our excerpts on ordinary A4 paper. We need to find the layout of the menu (only when we find the layout can we check our default paper size). After clicking on the layout, we click on the manuscript paper settings in turn.

Search for "printer" in the start bar. Click Printers and select Manage. Select printing preferences. Select paper/quality. The paper selection is A4. By default, the paper printed in this way is A4.

Start the target word document that needs to be modified, and click the File tab in the toolbar. Click the Print button in the pop-up toolbar to enter the print layout setting interface. Find the paper size format setting interface in the print typesetting setting interface, and click Select. Just change the A3 format of the document to A4 in the pop-up drop-down menu.
