The 8570 does not support Airprint/Mopria, so the plugin can't work.
Xerox is a MOPRIA partner so that cost should not be an issue, but Mopria is a selling feature for the 8580 in comparison to the older and no longer sold 8570, so that may be a limiting factor.
The only real avenue you have to get the plugin to work is to do a FER on the 8570 (Feature Enhancement Request), just understand that they may choose to not implement it since the machine was already replaced with a model that supports it (8580)
