Screen shot

I need to get screenshots of web page that extends beyond screen boundaries both horizontally and vertically. How can I do this?
When I take screenshots using modern or classic, I am getting only what is visible in the screen boundary. Please share a sample.
Thanks a lot,

You could use a Chrome extension for that, e.g. this one: GoFullPage - Full Page Screen Capture - Chrome Web Store

Thank you @ptrobot. Not allowed to do any installs. Is there any other way?

Thank you,

The other option is to print the web page to a pdf file.

I tried. PDF showing only what is visible as per the screen size. Am I missing anything?

Thank you,
