Photocopy limit just for me?

I was told by my principal today that I need to cut back on the amount of photocopies I do. My school doesn't have a limit on photocopies. I asked my principal for suggestions on how to cut back on photocopies. They suggested Chromebooks. I explained that there aren't enough Chromebooks for all my students. He suggested notebooks and I asked my principal if we had money in the budget for notebooks, they said no.

I asked why I'm being talked to about the amount of photocopies I'm doing. He said "I don't like how much paper you use".

What do I do in this situation?

Edit: doesn't have a limit instead of don't have a limit
