See https://web-platform-tests.org/writing-tests/print-reftests.html for some basic documentation. wptrunner supports this with the WebDriver executor and the "Print Page" command (https://w3c.github.io/webdriver/#print-page), which admittedly WebKit doesn't even support in the Automation Protocol layer (see bug 217173). This is, of course, not relevant to run-webkit-tests anyway. When it comes to run-webkit-tests: we have some support for printing to PDF in DRT, from https://commits.webkit.org/27519@main; we then added support for printing to PNGs in https://commits.webkit.org/49656@main, and https://commits.webkit.org/54361@main got rid of the last usage of printing to PDFs. Note that the last of these was not long after https://commits.webkit.org/52776@main, when WKTR got added; we don't seem to have support for printing to PDF in WKTR, even though it exists (albeit long unused) in DRT.
