+
+## Command line
+
+### MSI
+
+https://rustdesk.com/docs/en/client/windows/msi/#installprinter
+
+### EXE
+
+Install with the `--silent-install` argument, optionally followed by `printer=1` or `printer=0`.
+
+1. No `printer=1` or `printer=0` (default option):
+   - For a fresh installation, the printer driver will **not** be installed.
+   - For an update installation, the printer driver installation status depends on the previous version's settings.
+  ```shell
+  rustdesk.exe --silent-install
+  ```
+2. `printer=1` - Force install the printer driver:
+  ```shell
+  rustdesk.exe --silent-install printer=1
+  ```
+3. `printer=0` - Force not to install the printer driver:
+  ```shell
+  rustdesk.exe --silent-install printer=0
+  ```
+
+## After Setup
+
+If you need the RustDesk Printer while using the app, you can install it here:

+
+We don't offer a separate uninstaller for the printer. To remove it:
+  1. Go to Settings → Bluetooth & devices → Printers & scanners. Find RustDesk Printer, click it, then select Remove.
+  2. Alternatively, uninstall the main RustDesk application.
