I have vastly reduced the amount of printing I do. I do almost all of my reading on a tablet, for example. However, I do find that I'm more efficient at proofreading when I print out a draft, because I can write directly on it (and yes, I have an iPad Pro and a Thinkpad X1 Yoga, both with styli), attach PostIts, and the like. I recently bought a high-yield toner cartridge for my laser printer, and hope to live long enough to need another.
