Safari Reader missing images when printing to PDF
This is due to lazy image loading changes Safari made many months ago.
When using Safari Reader then Print -> Save as PDF, saved PDF files from many websites will be missing many or all of the images after the first page. Users won't notice this if they don't review the saved files, and may realize this months or years later when the original web pages are no longer available.

It's likely that Apple knows about this already, and as with many thousands or tens of thousands of other issues they know about, will continue to ignore them, focusing on new features instead, and will only address them if they gain enough visibility in the press.
If anyone else has the ability to complain about this issue, and other important issues, more loudly, maybe you'll convince Apple to care.
Is it not important to Apple to fix an issue causing customers' "archived files" to be missing important content?
