Details
User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:96.0) Gecko/20100101 Firefox/96.0
Steps to reproduce:
1.) Open newest Firefox browser (on Windows; probably it appears on other platforms as well)
2.) Open the following sample page:
https://www.thewindowsclub.com/how-to-create-new-local-account-in-windows-11
3.) Then click on menu:
File->Print preview
4.) Click on button "print" (and select your favorite PDF printer)
5.) Compare Webpage on screen with what is printed into PDF file:
Actual results:
As you can see a lot of vertical and (mostly) horizontal thin lines are inserted which are neither visible in Webpage nor in print preview.
No, they are not inserted by @media print CSS styles.
No, its not an error by the PDF printer driver (I have checked it with 3 different)
No, its not a general problem (these lines do not appear in PDF output when printed from Google Chrome).
No, it doesn't matter if "Shrink to fit Page Width" in Page Setup is enabled or not
So its a bug in Firefox.
Expected results:
Firefox should print a web page as displayed WITHOUT additional vertical and horizontal lines

The Bugbug bot thinks this bug should belong to the 'Core::Printing: Output' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.

I can reproduce the issue in Nightly98.0a1 Windoes10.

Also reproduces on macOS, despite using a completely different print-to-PDF backend.
Seems quite bad, but on the other hand it doesn't affect most pages AFAICT; there must be something about the structure/styling of this page that is triggering the issue for us.
