How can I set double-sided printing as default on my MacBook Air?

I am a college student and need 2-sided printing but my command for 2-sided printing is turned off and anytime I have to print something that more than 3 pages long and want to have 2-sided pages I have to keep going under printer options and click printer features and scroll down just to find 2-sided printing and keep turning it on but I want to have it on all the time because it helps me have less paper and also know I can just flip my paper over to the other side and know the next part of my work is on the back side. How do I turn it on indefinitely without having to keep doing these steps over and over again because it such a hassle and I just want to be able to get my work done without doing the little things. I have also looked up a lot of way to see if anyone else is having trouble but I can't find an answer and it's really starting to **** me off.
