Default [Q] Brother iPrint & Scan app and wifi direct

I have a Brother printer model MFC-375CW.

Currently I can print from my laptop to the printer when my phone is wifi tethered. I can only print from my phone when I have another device with wifi tethering turned on (I don't have a router. I only use the phone for internet).

Is it possible to configure wifi direct on the phone to print to the printer? Or perhaps another method to print from my phone to the printer directly?
