Split off from T181297 so that this won't be forgotten:
We should stop sending data for [[https://meta.wikimedia.org/wiki/Schema:Print|the Print schema]] (and possibly remove the instrumentation code entirely), once it is decided that no new data is needed (might be after some further deployments).
## Developer notes
Code that triggers events lives in WikimediaEvents extension: https://github.com/wikimedia/mediawiki-extensions-WikimediaEvents/blob/master/modules/all/ext.wikimediaEvents.print.js
#### Disabling
To disable the sending event please set the `wgWMEPrintSamplingRate` to 0. Current samplingRate is 0.1 (T176341).
#### Removing the feature
In order to remove the whole feature please remove the `ext.wikimediaEvents.print.js` file and deregister `schema.Print` and the `wikimediaEvents.print` module from extension.json `ext.wikimediaEvents` module.
