I found THIS documentation online. It states for Google Cloud Printing, you need the optional Wireless Print Solutions Adaptor, however, when looking at the Specs for that HERE it does not list the WorkCentre 6025 as a compatible device.
I would recommend calling into support and ask to speak with a 2nd Level Analyst for your device. Please have your serial number ready as they will need that to authenticate you. Here is the Contact Info
