Symptom

• Printer and barcode fonts for Seagull printer drivers are not listed in the printer properties -> fonts tab.
• They also are not listed in BarTender Designer as selectable fonts when a Seagull Printer Driver is selected.

Environment

• Windows 10/Server 2016 and higher
• Seagull Printer Drivers

Solution

There is a Windows setting that blocks untrusted fonts for newer Windows operating systems (Windows 10 / Server 2016 and higher). This setting basically blocks any fonts that are outside of the default %windir%/Fonts folder from being used. You can do the following to turn off this setting either using Windows Group Policy or through the Windows registry.

Windows Group Policy

1. Open the Group Policy editor (gpedit.msc) and browse to Computer Configuration\Administrative Templates\System\Mitigation Options\Untrusted Font Blocking

2. Verify this setting is off or logging without blocking untrusted fonts.

Windows Registry

1. Open the registry editor (regedit.exe) and go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Kernel\.

2. If the MitigationOptions key isn't there, right-click and add a new QWORD (64-bit) value, renaming it to MitigationOptions.

3. Right click on the MitigationOptions key, and then click Modify.

4. Make sure the base option is Hexadecimal, and then update the value data as indicated below. If there is an existing value, values should be saved during your update. For example, in some cases, if the current value is 1000, your updated value should be 1000000001000.

   • To turn this feature on. Type 1000000000000.

   • To turn this feature off. Type 2000000000000.

   • To audit with this feature. Type 3000000000000.

5.  Restart the system for the changes to take effect.
