I mean they kept it around for 10 years before killing it. They certainly tried.
It's printing physical paper. It's 2019, does it really confuse anyone as to why they would kill a product that prints paper? Even if it was successful in the short term, which it wasn't, it seems very rational to kill Cloud Print from a business perspective in the long term.
The developed world been moving far, far away from print for a while now. I imagine if you look at the graph of overall paper usage, you'll see it going down and to the right for some time into the future until it's near zero. Definitely the wrong business to be in.
It has no long-term prospects.
