Note:
Print watermarks support character printing and QR code watermarks. They are watermarks output during document printing, and their general settings can follow those of screen watermarks. Configure whether to set watermarks for headers and footers based on your actual needs.

5. You can print directly from the terminal or choose XPS printing. After saving the file in .xps/.oxps format, open it to see the effect.
Note:
XPS, short for XML Paper Specification, is an electronic file format developed by Microsoft. It is designed to provide a specification for document saving and viewing. Only Microsoft Office supports saving files in XPS format.
