The other advantage of a *good* HTML to PDF system is the ability to select multiple web pages, and combine them into a single PDF document, with sections in the correct order.
For example, try to print the NCSC CLoud Security Principles starting from https://www.ncsc.gov.uk/index/topic/151. Similarly try printing appropriate employment and tax pages. The next trick is to make it print double-sided.
I have - once- come across a system which would let you select the desired sections of a larger set of documents, then it would generate a single PDF of them all, in a suitable format for printing.
