What's new in Windows 10 KB5014666

With this update, Microsoft is introducing a bunch of new Print and Scan features, including support for the Internet Print Protocol (IPP) on USB printers.

The Internet Print Protocol allows you to print and manage documents on a Windows print server directly over HTTP. While Microsoft has supported IPP in network printers, with this update, Microsoft is also supporting IPP over USB.

"Microsoft has supported Internet Print Protocol (IPP) for network printers starting in 2018 with the release of Windows 10, version 1809. We are now expanding IPP support to USB printers," explains the update's release notes.

Other new printer features include:

• Print support app (PSA) APIs – Using the PSA framework, printer manufacturers can extend printer functionalities and user experience. For more information, see Print support app design guide.

   

• PIN-protected printing for IPP and Universal Print - Standard print dialogs now include a user interface to enter a PIN code.

   

• eSCL Mopria Scan protocol - Windows now supports the eSCL Mopria Scan protocol. It can be used with Mopria certified scanner devices.

   

In addition to the new printing features, the Windows 10 KB5014666 cumulative update preview includes twenty-six other improvements or fixes, with the two highlighted ones below:

• Addresses a known issue that might prevent you from using the Wi-Fi hotspot feature.

   

• New! Adds IP address auditing for incoming Windows Remote Management (WinRM) connections in security event 4262 and WinRM event 91. This addresses an issue that fails to log the source IP address and machine name for a remote PowerShell connection.

   

• New! Adds Server Message Block (SMB) redirector (RDR) specific public File System Control (FSCTL) code FSCTL_LMR_QUERY_INFO.

   

After installing this update, Windows 10 20H2 will be updated to build 19042.1806, Windows 10 21H1 will be updated to build 19043.1806, and Windows 10 21H2 will be updated to build 19044.1806.
