AI Summary: Implement support for connecting to printers directly via serial, USB, and socket APIs in the QZ Tray browser plugin. This is necessary to address Microsoft's deprecation of third-party printer drivers in Windows, allowing users to continue printing to devices without relying on outdated drivers. The task involves expanding the plugin's configuration options to include connection parameters for these alternative methods and potentially incorporating printer discovery mechanisms like mDNS/Bonjour for improved user experience.
