Microsoft Confirms Windows 10 KB5014666 Update Breaks USB Printers


Microsoft has confirmed that the optional update for Windows 10 (KB5014666), released on June 28, 2022, to add new printing features and notable fixes, will affect some printing devices after the update is installed.

According to the company, the bug causes Windows 10 to show duplicate copies of printers installed on a device, usually with a similar name and the “Copy1” suffix. Also, applications that refer to the printer by a specific name cannot print a document. The update also affects normal printer usage and normal print operations may be interrupted, causing print operations to fail.

The Redmond giant says it is working on a new update to address the issue in a future update. Meanwhile, users experiencing issues can use the Feedback Hub to submit a report and try workarounds that may help resolve the issue:

  • Open the Settings app, go to “Bluetooth & Devices” and select “Printers & Scanners”
  • If there appears to be a duplicate installation of an existing printer, such as with the “Copy1” suffix, verify that printing works for this printer. This printer should work as expected.
  • If you need to use the original printer installation and not the duplicate, right click on the duplicate printer, select “Printer Properties” and select the “Ports” tab. Observe the port in use.
  • Open “Printer Properties” on the original printer and select the “Ports” tab. From the list displayed, select the port option used by the dual printer. If this original printer works normally, the duplicate copy printer can be removed.

If the problem persists, Microsoft recommends performing the following steps:

  • Update the printer driver for your device. See Install the latest driver for your printer for help.
  • If you already have the latest driver, check the printer manufacturer’s website for possible firmware updates for the device
  • If you’re still having problems, uninstalling and reinstalling your printer may help.
  • Turn off your printer and disconnect all cables
  • Open the Settings app, go to “Bluetooth & Devices” and select “Printers & Scanners”
  • Select the appropriate printer and select the “Remove device” option
  • Restart your device
  • Turn on your printer and reconnect it to your device

Microsoft is currently investigating the issue and will provide an update as more information becomes available. According to the Windows Health Dashboard, the affected platforms are Windows 10 21H2, 21H1, and 20H2 (including Windows Server version 20H2).
