Restarting your device and checking for updates might help the troubleshooter apply sooner. For more information, see keeping your device running smoothly with recommended troubleshooting. A troubleshooter has been released which will automatically download and resolve this issue on affected devices. If you have an affected installed printer, you can use the above workaround or wait for your device to be mitigated automatically. Important: KB5016691 prevents this issue but will not affect already installed printer drivers. Resolution: This issue was resolved in KB5016691. For instructions, please see Download printer drivers in Windows. Workaround: If you have an installed printer which only allows default settings, you can mitigate this issue by removing and reinstalling the printer. You might be affected by this issue if your printer is unable to use printer specific features such as color, two-sided/duplex printing, paper size or type settings, or resolutions higher than 300x300dpi. Without connectivity, the printer is set up with default settings and in some scenarios might not get updated once connectivity to the printer is restored. Windows needs connectivity to the printer to identify all the features of the printer. Microsoft has found an issue when an installed printer uses Microsoft IPP Class Driver or Universal Print Class Driver and is installed on a Windows device with connectivity issues to the printer.

Printer drivers installed during connectivity issues might only have default features
