idk why I never thought of this but apparently you can straight up `cat` files to a physical printer
If your file only contains text can literally just do
`cat myfile.txt | netcat <printer-ip> 9100`
At least with my printer here it worked
I also tried with a pdf file but it never seemed to print hmmmm

No that I'm particularly interested in doing that but at least now I can literally printout the man pages to have a nifty little physical man pages book
