Hie there,
Yes, you can surely make a living by selling prints.
Selling the original will make good or great money once, but you can continue to make money off of one work of art by selling prints. ... You can sell prints online through your own store or by using a print on demand service. You can also sell prints at a physical location—like at an art festival or street fair..
You can also sell your work on image submission sites which are free of cost.
