How to retain the formatting of Apple Notes at export?

I want to export some notes as PDFs or any other type of text file to save them locally, but when I go to *File -> Export as PDF...* it shrinks down the note page width, meaning the lines of code and my notes look completely different than what I have formatted them to look like. I am not 100% sure, but if I remember correctly, about 6 months ago I, somehow, managed to retain the width of the note window and its dark background while exporting a note. How can I export my notes with the correct formatting? MacOS Monterey / version 12.6 / MacBook Pro 2016
