Network protocols for printing on a LAN are quite old. LPD and SMB are two that I use at home. I know I am an advanced user and this won't solve it for the masses, but if I combine that with ssh I can already print anywhere. So I don't completely understand why you need a proprietary Google "cloud" service that they can sunset some years later and break. When I heard about this I wondered why someone can't build a consumer-friendly solution on these older protocols. Of course, printing itself is less relevant than it was 20 years ago, so it's not exactly a booming industry.
