+
+**Printer** has first class support from 🐊**Putout** with help of [`@putout/plugin-printer`](https://github.com/coderaiser/putout/tree/master/packages/plugin-printer#putoutplugin-printer-). So install:
+
+```sh
+npm i @putout/plugin-printer -aD
+```
+
+And update `.putout.json`:
+
+```json

+    "printer": "putout",
+    "plugins": [
+        "printer"
+    ]
+}
+```
