ZSDK_DemosAndroid Program: ZebraPrinterLanguageUnknownException


Hello. I'm testing the connection to a ZTC ZT230-203dpi ZPL printer. I tried using the demo program ZSDK_DemosAndroid provided in the link-os sdk package. However, a ZebraPrinterLanguageUnknownException is thrown when this line of code is being run:
printer = ZebraPrinterFactory.getInstance(printerConnection);

Here's the URL of the printer:

Any ideas? Thanks in advance!
