It doesn't really work out that way though. People who don't need to print very often end up churning through absolutely garbage printers that are more trouble than they're worth and don't last very long before the ink dries up and leaves it a pile of junk. People who print a ton can instead invest a tiny bit more in a printer with notably cheaper per-print costs. It's really better viewed as almost an instance of the Sam Vimes "Boots" theory.
