It is possible to print QR Codes on a console using for instance this solution. There are other methods available on github too, but all of them end up displaying UTF8 chars. Therefore, I think that the challenge is in displaying a stdout on the TTY1 from the remote host
The remote host is a linux deployment without X, it has connectivity, allows me to ssh, I'm able to become a super-user and it has a local monitor connected displaying the login prompt on TTY1 (which is where I want to print the QR code).
