This bug has been originally reported at AdoptOpenJDK here:
https://github.com/AdoptOpenJDK/openjdk-build/issues/1277

In an Citrix remote desktop scenario on Windows 10 an incorrect default printer is being returned by javax.print.PrintServiceLookup.lookupDefaultPrintService(). Example code:

public class PrintServiceLookupTest {
       public static void main(String[] args) {
             javax.print.PrintService service = javax.print.PrintServiceLookup.lookupDefaultPrintService();
             if (service != null) {
                    String printServiceName = service.getName();
                    System.out.println("Default print service name (" + printServiceName+")");
             } else {
                    System.out.println("No default print service found.");
             }
       }
}

Steps to reproduce:

1. Logon to session Citrix or RDP
2. set a local or network default printer
3. run the code "PrintServiceLookupTest".
4. set a redirected default printer
5. run the code "PrintServiceLookupTest".

The registry key used for local or network printers is:

HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows\Device

The registry key used for redirect printers is:

HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows\SessionDefaultDevices\ "session" \Device

It looks like OpenJDK isn't using the correct registry key for the RDP/Citrix use case. This isn't an issue on a default host Windows OS. So a remote setup via Citrix is necessary to reproduce.

Actual output:
Some printer which isn't the redirected default printer.

Expected output:
Same as this windows query:
