Returns: 1 = success
0 = error
XIJET_GetPrinterParameter will return a single printer configuration parameter. ParameterIndex dictates which
parameter will be returned, while pParameter points to an appropriately sized memory field. Defined constants
for ParameterIndex are located in XIJET_API.h. The optional parameter HeadNumber should only be included
for head specific parameters, such as trigger offset distance.
For example to read the printers print queue depth setting:
int Success;
USHORT value;
Success = XIJET_GetPrinterParameter( printerHandle, XIJET_QUEUE_DEPTH, &value);
See Appendix A for list of adjustable printer parameters.

根据C ++ doc，方法签名应为：
public static extern int XIJET_GetPrinterParameter(IntPtr printerHandle,
Uint16 parameterIndex,
IntPtr pParameter, UInt16 headNumber);
您可以在此处查看类型转换表：

我自己一直在努力，但我确实找到了解决方案：
Public Declare Function XIJET_SetPrinterParameter Lib "XIJET_API" (ByVal printerHandle
As IntPtr, ByVal parameterIndex As UShort, ByRef pParameter As UShort,
ByVal HeadNumber As UShort) As Short
