Not how printing as pdf works but I appreciate the effort

I haven’t looked at the printer driver interface on various different operating systens, but I imagine programmatically you don’t write ACSII text directly to it, the way you would with file io calls. Though on Linux you have “lpr” where you can pipe text directly to the command. It’s possible a printer could natively support this, but clearly it would be a different interface to render anything more complex than ascii text.
