你有一个主意吗？文档的摘录是

    int xijet_getPriNterParameter（句柄打印机手机，//返回从打开呼叫返回的    ushort参数index，    PVOID PPARAMETER，    ushort headNumber = 0）;//当适用    回报：1 =成功    0 =错误    Xijet_getPriNterParameter将返回单个打印机配置参数。参数指示决定了哪个    参数将被返回，而PPARAMETER指向适当大小的内存字段。定义的常数    对于参数inderex，位于xijet_api.h中。可选的参数头缩写仅应包括    对于头部特定参数，例如触发偏移距离。    例如，读取打印机打印队列深度设置：    int成功；    吸管价值；    成功= Xijet_getPrinterParameter（打印机，xijet_queue_depth和value）;    有关可调打印机参数的列表，请参见附录A。
