If there's something that Google loves as much as launching exciting new projects (say hello Stadia and Duplex on the web!), it's been killing them for a few years now and we now have an expiration date for Google Cloud Print. The service launched by 2010 as a way to make printers more accessible to Chrome OS, but 9to5Google points to a post on the support site suggesting that services its no longer needed.
Google rightly notes that it has improved the native support printer in Chrome OS, but Cloud Print is a welcome link from all sorts of devices to printers that we know, love and are endlessly frustrated with when they refuse to work. Its easy to connect with others services has helped more than once, but now we are heading to one-by-one settings and different ones applications printing.
If the service is used, then by the end of 2020 you will have to work out an alternative, because when the lights come on in 2021 - the devices in all Operating Systems will no longer be able to print using Google Cloud Print. Cloud Print has never reached beta.
