Microsoft is working on a resolution and will provide an update in an upcoming release. |

After installing this update, devices which attempt to connect to a network printer for the first time might fail to download and install the necessary printer drivers. Devices which had connected to and installed the printer prior to the installation of this update are unaffected and operations to that printer will succeed as usual. This issue has been observed in devices which access printers via a print server using HTTP connections. When a client connects to the server to install the printer, a directory mismatch occurs, which causes the installer files to generate incorrectly. As a result, the drivers may not download. 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 KB5006743. |
|
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 KB5007236. |
|
After installing this update, you might receive a prompt for administrative credentials every time you attempt to print in environments in which the print server and print client are in different times zones. Note The affected environments 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 was resolved in KB5006743. If after installing KB5006743 you still receive the prompt every time you print, see Q1 in the "Frequently ask questions" section of KB5005652—Manage new Point and Print default driver installation behavior (CVE-2021-34481). |
