Note: Only printers with English-only names are supported.

If selected, the installer creates a startup entry for SQLMessenger in Windows Task Scheduler, so the application launches automatically when Windows starts.

If the "Automatically start SQLMessenger at Windows startup" option is enabled, SQLMessenger will start automatically under the current user’s credentials when Windows starts. After clicking Next, enter this user’s Windows login password to create the startup entry.
