How can I print all project files at once in a “beautiful” stylized form?

Question

Seal

I thought about printing the project files on paper, for greater clarity, but here's how to quickly do it, so that the code styling would be with syntax highlighting and immediately print all the files from the selected folders?
I looked for extensions, but they can only print a selected section of the file, but I would automate the process.
By principle, go through all the files in the folders and print each one with the same syntax as in the editor. I use VS Code, but it's not that important.
