Install Zebra Browser Print, or start the Zebra Browser Print Service

I have a GX430t label printer installed, I can print tests to if from the printer driver no problem. Its connected by USB. I have installed Zebra Browser print application and I am able to select the printer OK. When I visit the sample page..

file:///C:/Program%20Files%20(x86)/Zebra%20Technologies/Zebra%20Browser%20Print/ZebraBrowserPrintDocsWebCodeExamples/sample/index.html

I get t he request to add local host but then an error message "An error occured while attempting to connect to your Zebra Printer. You may not have Zebra Browser Print installed, or it may not be running. Install Zebra Browser Print, or start the Zebra Browser Print Service, and try again."

Can anyone point me in the right direction? I've tried deleting the printer driver and reinstalling everything 3 times already. No luck.
