Improvements and fixes

This security update includes quality improvements. Key changes include:

• Addresses a known issue that might prevent devices from downloading and installing printer drivers when the devices attempt to connect to a network printer for the first time. We have observed this issue on devices that access printers using a print server that uses HTTP connections.
• Addresses a known issue that might ask for administrative credentials every time you attempt to print. This occurs in environments in which the print server and print client are in different times zones.
  For more information about the resolved security vulnerabilities, please refer to the Security Update Guide website and the October 2021 Security Updates.

Known issues in this update

• Perform the operation from a process that has administrator privilege.

• Perform the operation from a node that doesn’t have CSV ownership.
  Microsoft is working on a resolution and will provide an update in an upcoming release.
  After installing this update on a print server, printing properties defined on that server might not be correctly provided to clients. Note this issue is specific to print servers and does not impact standard network printing. This issue will not cause printing operations to fail, however, custom settings defined on the server – for example, duplex print settings – will not be applied automatically, and clients will print with default settings only.This issue results from an improper building of the data file which contains the printer properties. Clients which receive this data file will not be able to use the file content and will instead proceed with default printing settings. Clients who have previously received the settings package prior to the installation of this update are unaffected. Servers which use default print settings and have no custom settings to provide to clients are unaffected.Note The printer connection methods described in this issue are not commonly used by devices designed for home use. The printing environments affected by this issue are more commonly found in enterprises and organizations.| This issue is resolved in KB5007245.
  After installing this update, Windows print clients might encounter the following errors when connecting to a remote printer shared on a Windows print server:

• 0x000006e4 (RPC_S_CANNOT_SUPPORT)

• 0x0000007c (ERROR_INVALID_LEVEL)

• 0x00000709 (ERROR_INVALID_PRINTER_NAME)
  Note The printer connection issues described in this issue are specific to print servers and are not commonly observed in devices designed for home use. Printing environments affected by this issue are more commonly found in enterprises and organizations.| This issue is resolved in KB5008255.
