Get Settings from USB Printer not working as expected

I am trying to print a list of settings from my KR403 to my debug log like in the SDK Documentation example for the SettingsProvider Interface, but it is not working as far as I can tell.  I copied the displaySettings function right out of the example into my test application, switched the printl commands with Log.v and called it in between connection.open and connection.close. (My base code is the USBDiscoverer example) This is my function:

 

private static void displaySettings(Connection c) throws ConnectionException, ZebraPrinterLanguageUnknownException, SettingsException, ZebraIllegalArgumentException {         ZebraPrinter genericPrinter = ZebraPrinterFactory.getInstance(c);         ZebraPrinterLinkOs linkOsPrinter = ZebraPrinterFactory.createLinkOsPrinter(genericPrinter);           if (linkOsPrinter != null) {               Log.v("PRINTER", "Available Settings for myDevice");             Set<String> availableSettings = linkOsPrinter.getAvailableSettings();             for (String setting : availableSettings) {                 Log.v("PRINTER", setting + ": Range = (" + linkOsPrinter.getSettingRange(setting) + ")");             }               Log.v("PRINTER", "Current Setting Values for myDevice");             Map<String, String> allSettingValues = linkOsPrinter.getAllSettingValues();             for (String settingName : allSettingValues.keySet()) {                 Log.v("PRINTER", settingName + ":" + allSettingValues.get(settingName));             }         } } 

 

No exceptions are thrown, and I get no output except this:

Am I missing something obvious in my test implementation?  Does the KR403 operate differently?  How can I get this to work as I expect?

 

Thanks.
