ZBRPrinter.dll and ZBRGraphics.dll compatibility with ZXP Series 7 card printer drivers - version 3.02.00


We have an application that uses these DLLs to control the card printer, we need to know if the drivers are compatible with the latest drivers for the ZXP Series 7 printer.
ZBRPrinter.dll - Version - Date 1/7/2009
ZBRGraphics.dll - Version 2.2.8 - Date 3/25/2009
Our application is issuing a call to ZBRGDIIsPrinterReady() it returns false, when it should be returning true.

Also we would like to know if there is a way to get the Zebra Motif Series Printer Emulator - ZXP to run in USB mode.
