Devices which had connected to and installed the printer prior to the installation of KB 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. Only the automatic download and installation processes are impacted by this issue. After installing KB or later updates, 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. If after installing KB you still receive the prompt every time you print, see Q1 in the "Frequently ask questions" section of KB—Manage new Point and Print default driver installation behavior CVE After installing KB or a later update, certain printers in some environments using Point and Print might receive a prompt saying, "Do you trust this printer" and requiring administrator credentials to install every time an app attempts to print to a print server or a print client connects to a print server.
This is caused by a print driver on the print client and the print server using the same filename, but the server has a newer version of the file. When the print client connects to the print server, it finds a newer driver file and is prompted to update the drivers on the print client, but the file in the package it is offered for installation does not include the later file version.
Workaround: Verify that you are using the latest drivers for all your printing devices and where possible, use the same version of the print driver on the print client and print server. Resolution: This issue is resolved externally by adjusting the print drivers in your environment. If updating drivers in your environment does not resolve the issue, please contact support for your printer manufacturer OEM.
