ArcGIS Online/Portal printout for a Web Map TIle Service (WMTS) service does not maintain the scale level at which the map is viewed from, 4 levels zoomed in and shifted from original extent. This is due to how the web map as JSON is built by the Java Servlet Application Programming Interface (JSAPI).

Will Not Be Addressed
The development team has considered the issue or request and concluded it will not be addressed. The issue's Additional Information section may contain further explanation.
Under the hood, the map viewer adds the layer as a WebTiledLayer, not as an WMTSLayer. This explains why the layer is sent as WebTiledLayer.
