+For network-enabled ESC/POS compatible printers, provide the printer's IP address in the `PRINTERS` variable. Once configured, you can print vouchers directly to your network printer from the UniFi Voucher Site application.

 Just like with PDF printing, navigate to the voucher and click on the "Print" button. The application will send the print job directly to the ESC/POS printer over the network, ensuring quick and seamless voucher printing. Make sure your printer supports ESC/POS commands and is correctly configured to accept print jobs over the network.

 ## Migration Guide

+### Migration from 5.x to 6.x
+
+When upgrading from 5.x to 6.x, the following changes need to be made:
+
+1. **`UI_BACK_BUTTON` Removed**
+
+    - The `UI_BACK_BUTTON` configuration option has been **removed** in 6.x.
+    - This setting is no longer used and can be safely **removed from your environment configuration**.
+
+2. **Printer Configuration Changes**
+
+    - The legacy printer configuration options **`PRINTER_TYPE`** and **`PRINTER_IP`** have been replaced by a single setting: **`PRINTERS`**.
+    - The new format is a **comma-separated string** combining the printer type and IP address.
+
+    **Before (5.x):**
+
+    ```env
+    PRINTER_TYPE='pdf'
+    PRINTER_IP='192.168.1.10'
+    ```
+
+    **After (6.x):**
+
+    ```env
+    PRINTERS='pdf,192.168.1.10'
+    ```
+
+    - Update your configuration to use `PRINTERS` and remove the old `PRINTER_TYPE` and `PRINTER_IP` variables.
+
+> Make sure to clean up any deprecated variables and update your printer configuration to ensure compatibility with 6.x.
