What is the Printer USB Virtual COM Port Windows Driver?
The Printer USB Virtual COM Port Driver is a special driver used by certain printers that connect via USB and are configured to communicate with a computer as if they were connected through a serial port (COM port), rather than a standard USB device. This method of communication is often used for legacy or specialized printers that need to operate in an environment where serial port communication is required (e.g., older systems, industrial settings, or certain POS systems).
In simple terms, it allows a USB printer to emulate a serial (COM) port connection, so the operating system treats the printer as though it is using a traditional serial interface (RS-232) rather than the more modern USB protocol. This is often the case in environments where legacy software expects printers to be connected through a COM port.
