Microsoft didn't specify whether a particular Windows update caused the problem, only that Windand above are affected by the vanishing USB printer port issue. Windows will not be able to complete any task that requires that port," Microsoft said. "If you connect a USB printer to Windows 10 version 1903 or later, then shut down Windows and disconnect or shut off the printer, when you start Windows again the USB printer port will not be available in the list of printer ports. The vanished port pretty much means print jobs won't work anymore but, according to Microsoft, it only happens if the computer and printer are shut down in a specific order. Microsoft said the USB printer port is missing after disconnecting or turning off a printer while Windows version 1903 and later are shut down. The reports emerged as Microsoft published a support note on Wednesday detailing an issue affecting Windand later with USB-connected printers.
