Posting this as an fyi as I spent a helluva day to get Google cloud print working. All the issues are in the Xerox documentation which is pointless and awful. (Love the printer may never buy Xerox again for their documentation problems)
Ok, to the point, to enable Google cloud print (GCP) 1) get the ip address of your printer. 2) visit http://ipaddress 3) enable GCP (properties|port enabling) 4) enable https (security | ssl tls). Generate a certificate , enable ssl, enable sslv3, smtp => starttls 5) after all the reboots, go to https://ipaddress 6) protocols|Google cloud print 7) click register this device with Google 8) a printout will occur with a URL to visit while signed into your Google account.
Was that so hard Xerox that the only step you included was the #7 with absolutely no background??!
