I understand the desire to have the least amount of impact on sheet designers since a bunch of sheets are probably nearly abandoned, but there's only one way to improve printer support among them: enable the feature and let them fix their sheet. Like enabling print support would let people print out compendiums and licensed content. It's not a hard fix but the roll20 team has to deal with things that I don't. Most sheets should just work by playing with the zoom percentage in the print window.

I have a specific one for the Neceros pathfinder sheet but I haven't decided if I'm going to create new userstyles for each edge case or make a way to 'detect' it. This one should work for most sheets and the 5E one.

I don't know why I didn't make a userstyle before but I'm losing my mind with how many notifications I'm getting from this thread.

If it doesn't work for your sheet I can create some fixes but it should just let you open up a character sheet and press ctrl + p and it'll print.
