+# Create & Remove Windows Print Service
+This example explain how to create and remove windows print service with nssm.exe and communicate with browser with websocket server.
+
+## Requirements:
+- Install nssm http://nssm.cc/download and store into root directory
+- Create ESCPOS PHP (In my case, I use https://github.com/mike42/escpos-php) to communicate with ESCPOS Printer Devices in www directory
+- Install Hoa Project / Workerman to create websocket server to communicate with browser
+  - Hoa Project <https://github.com/hoaproject/Websocket> (Read Only Repository)
+  - Workerman <https://github.com/walkor/workerman>
+- Create log file to store printer status and activities in www directory
+- set this value `"start_fullscreen": true` in `settings.json`
+
+## Directery structure
+```
+php/
+    - php.exe
+www/
+    vendor/
+    composer.json
+    composer.lock
+    - index.php
+    - install-print-service.php
+    - remove-print-service.php
+    - printer-server.php
+    - printer.log
+nssm.exe
+```
+
+## If this example may useful for you, please give me feedback
