Specific operation steps: 1. Open the document you want to print, and then click File → Print → Print. Please do not select quick print, this is the default print, and the print parameter debugging window will not pop up.

2. In the pop-up "Print" setting dialog box, click the "Property (P)" column to set the printer parameters.

3. Switch the tab to "Page Setup", and you can choose "portrait" and "landscape" in the page direction. Printers are portrait by default, and portrait printing is the most commonly used. If it is not vertical, select to change it to vertical.
