A DESCRIPTION OF THE PROBLEM :
Hi support,
the problem occurs in Citrix or RDP session when you set a default printer redirected.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Logon to session Citrix or RDP
2. set a local or network default printer (Microsoft Print to PDF)
3. run the code "PrintServiceLookupTest".
4. set a redirected default printer (Invia a OneNote 16 (from WKST015))
5. run the code "PrintServiceLookupTest".


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Print Service Default Name is (Invia a OneNote 16 (from WKST015))
ACTUAL -
Print Service Default Name is (Microsoft Print to PDF)

---------- BEGIN SOURCE ----------
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("Stampante di default (" + printServiceName+")");
             } else {
                    System.out.println("Nessuna stampante di default trovata");
             }
       }
}
---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
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

In these links you can find workarounds, but only until you change your default printer
