Routine Description:

    IPrintOemUni EnablePDEV interface
    Construct its own PDEV. At this time, the driver also passes a function
    table which contains its own implementation of DDI entrypoints

Arguments:

    pdevobj        - pointer to a DEVOBJ structure. pdevobj->pdevOEM is undefined.
    pPrinterName   - name of the current printer.
    Cpatterns      -
    phsurfPatterns -
    cjGdiInfo      - size of GDIINFO
    pGdiInfo       - a pointer to GDIINFO
    cjDevInfo      - size of DEVINFO
    pDevInfo       - These parameters are identical to what39s passed into DrvEnablePDEV.
    pded: points to a function table which contains the system driver39s
    implementation of DDI entrypoints.
