Would there be any interest? header tags are used to make table of contents, anchor tags create Index entries, all the formatting tags (tables, un-numbered and numbered lists etc) do basic print formatting. All the bold/underline/italic also render to paper. Sort of like a poor man's TeX.
I used to write my papers in HTML and a custom print CSS file I made so it fits the school's formatting requirements. It worked surprisingly well. Just write HTML, and then just print it, as basic as it gets. That was easier than bending LaTeX to the school's template which was in MS Office format.
Always frustrates me how underutilized @media print is. Always liked crafting some good CSS for it on sites, especially ones that I worked on that were document heavy.
I use this one, and it's pretty nice: https://weasyprint.org/. They implement their own rendering engine so its support of new features and edge cases isn't the best, but every problem I've run into with it has been solvable with a little work. I really like it for laying out printed forms!
I write business letters in HTML. I have a custom letter.css and a base letter.html+.js that loads individual letters into a template. I have some custom tags for date, address and similar. The individual docs are super clean. I can export compiled html files with embedded css (no js needed) and images that render perfectly and are even smaller then the pdfs I export (print) and those are small too.
Two downsides. The biggest problem, I didn't find a way to do proper multi page docs. And especially Firefox has limited print css support.
Second: everything is crudely hacked together and in no way usable by others...
maybe chatgpt can rewrite the code better, so I can publish it?
Thanks all - It seems there are many ways to do this, or perhaps just write the document in markdown and print it that way. I mean I guess I could always install and lear TeX (again) too.
