This is great if you can pull it off. Do you have any school aged kids? I'd say 80% of our printer use is for school projects or forms that have to get printed out, signed, and physically handed back in. Not sure how we could get by without one.
With that being said, when we did buy a printer about 5 years ago we bought a monochrome Brother laser printer and it's a way better investment than inkjet printers (if you don't need to print pictures or something)
When I dealt with this in school, I would simply fill the answers in on a separate document. Make sure answers are labeled correctly. Scan in notebook drawings if needed. I haven't had a printer in decades. If I absolutely have to get something printed out, I go to the library or print shop.
I have two school age kids, and yes, that's been a constant battle. Teaching them to think about how to be able to submit projects electronically has been a learning curve for all of us.
