Blueprint PrintScout and Microsoft Windows 10

Version 2

    Background

    Pharos Blueprint Enterprise Service Pack 1 for version 5.2 (released December 2015) provided the first PrintScout that was compatible with Microsoft Windows 10. Since that time, Microsoft has released an Anniversary and Creators update for the operating system, in addition to regular product updates.

     

    Problem Statement

    Upon installing the May updates for Microsoft Windows 10, fonts in applications or the operating system may not display properly:

    Root Cause

    At issue is the "application injection" that occurs as part of the operation of PrintScout. The injection seeks to determine what application creates a specific Windows Spooler command so that the software can appropriately track the name of the application (winword.exe, iexplore.exe, notepad.exe, etc.) that generated the print job. As a result of the May updates (including Creator), an operating system application is faulting.

     

    Resolution

    Exclude the "fontdrvhost.exe" application from injection. On the Collector hosting Trackers, go into the Blueprint Administrator application and:

     

    1. Go to Print Scout > Settings > Application Tracking.
    2. In the “App Name Exclusions” box, click Add and then type fontdrvhost.exe and Apply that change.

     

     

    As the Scouts check in or are installed, they’ll get the new setting, and things will be back to normal. If you wish to disable application injection entirely for a single workstation or subset of workstations, the following can be deployed as a .REG file to the install base:

     

    Windows Registry Editor Version 5.00
    
    [HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\PharosSystems\PrintAgent\AppTracking]
    "Enabled"=dword:00000000
    

     

    Once applied, the PrintScout service would require a restart to take effect.
