1. What kind of printers can I print to using Google Cloud Print?
   
   Google Cloud Print can print to Cloud Ready printers, which connect directly to the web and don’t require a PC to setup. Google Cloud Print can also connect to existing (classic) printers that are plugged into a Windows, Mac, or Linux computer with Internet access, using the Google Cloud Print connector in Google Chrome.
   

 

I have an HP printer that's about 7-8 years old, USB only.
I set everything up in Google cloud print, and use an app called "Cloud Print" from the Play Store.
Works great. I think I paid about $1.50 for the app. Contrary to what the instructions say for the app, I don't need to have Chrome running, or keep my printer turned on. When I'm ready to print, I tap the print button in the app, and my printer turns on and works fine.

 

You can use PrinterShare or Google Cloud Print. Both apps work well. PrinterShare is a paid app while Google Cloud Print is free. Neither app requires your printer to be on if it has Wi-Fi capabilities.
