Win 10 Bug Affects USB Printer Ports

Microsoft lists two main causes for the Win 10 glitch that causes the USB printer port to become unavailable for carrying out printing commands.

“If the driver for the USB printer contains a Language Monitor, the OpenPortEx callback function of the Language Monitor would not be called. As a result, the user cannot fulfill operations dependent on the operation of the Language Monitor,” it explains.

“In the ‘Devices and Printers’ control panel, when selecting [Print Server Properties] > [Port] tab, the port for the USB printer (such as ‘USB001’) would not appear in the list of printer ports.  As a result, the user cannot fulfill operations dependent on the existence of the port.”

Microsoft is currently working on the Win 10 printer bug fix and may soon provide more information when it releases one. As for now, affected users will have to replace their printer’s driver or uninstall Win 10’s latest updates. Those who’ll uninstall Win 10 updates may want to install a bunch of security updates.
