Ubuntu 18.04 CUPS + Google Cloud Print
In 2020 Google pulled the plug on Google Cloud Print and with it much functionality for larger business, school and enterprise copiers and printers. Please see the recent blog post about one feature recently added to CUPS on Chrome "Input Tray" paper selection.
This is an alternative tutorial to Google's officially maintained Google Cloud Print Connector. This tutorial does not require Chromium to be installed on the Ubuntu computer. This could also be done in a very similar manner on Rasbian, Raspberry PI for a very low profile and low energy print server. My tutorial was for Kyocera's new printers 2019 series of TaskAlfas which have Google Cloud Printing built in but are still lacking some functionality. This setup allowed us to use the PPD's provided by Kyocera in order to get all the functions available under the More Settings -> Advanced Settings dialog.
