Question how to set hl-l2390dw brother printer to be always on so i dont have to get up every time for it to print

hl-l2390dw brother

first is it a good idea to have it always on? any cons.?

how to do it?
Having it on 24/7 can shorten its life by maybe 20% maybe more or less but not to drastic the main issue is constant power flow wears parts out more then on off. However just like leaving it on powering it on and off can damage other parts more as well so real question is what doesn't wear the life down anymore....

To get it to stay on goto to settings and like with a PC power setting sleep/hibernate state and shut off... if there's also a feature for auto off shut that off aswell
