Google Cloud Print is dead. RIP, 2010–2026. But its spirit lives on in other cloud services. Try PrinterShare or Epson iPrint. These apps let you email a document to your printer. From anywhere.
You can be in a coffee shop in Paris. Your iPad shoots a file to a server. That server whispers to your printer in Ohio. Magic from space. Just make sure your printer is turned on. A warm printer in Ohio is better than a cold one in Paris.
