Every Windows version has its own set of issues, and there are some which take an extended time to resolve. One such error is where the USB printer goes missing. It applies to Windows 10 1903 and Windows 10 2004. The precise error message is:
USB printer port missing after disconnecting printer while Windows 10 is pack up.
In this post, we’ll show how you’ll resolve this issue employing a workaround.
In this scenario, if a user shutdown Windows while the USB printer is connected or directly disconnects the printer, then it’ll not be available within the list of printer ports when reconnected or when the pc is restarted. therefore the problem is that the port goes missing, and if Windows tires to finish any task that needs that port, it’ll not work.
You can verify by getting to Settings > Devices > Printers & Scanners > Print Server Properties > Port tab.
If you check for the USB port related to that printer, it’ll be missing. The affected printer and therefore the USB port that it’s connected to shouldn’t be displayed on the page.
Workaround for USB Port Missing error
The resolution is straight forward—all you would like to show on the printer before starting Windows and keep it connected over USB. Windows will automatically detect the printer and therefore the port related to it. If you’re using the port for something else, it’ll be available.
You will need to keep repeating this unless the workaround becomes available. It’ll become available to Windows users via the update.
Another workaround are often if you’ve got a router with a USB port. You’ll hook up with the router, and access it through the network. It essentially relieves you from ensuring to stay printer all time.
That said, there are two causes of the matter.
• If the driving force for the USB printer contains a Language Monitor, the OpenPortEx callback function of the Language Monitor wouldn’t be called. As a result, the user cannot fulfill operations hooked in to the operation of the Language Monitor.
• Within the “Devices and Printers” instrument panel , when selecting [Print Server Properties] > [Port] tab, the port for the USB printer (such as “USB001”) wouldn’t appear within the list of printer ports. As a result, the user cannot fulfill operations hooked in to the existence of the port.
The technical background for the matter is that they appear to be using USB Redirection Feature, where rather than the local port, a virtual port is in use.
Microsoft has confirmed that this is often a drag and that they are working to repair the difficulty during a future version of the OS.
