概述
Foxit PDF SDK 在 Windows 环境下提供了名为 PDFPrintManager 的 PDF 打印管理拓展库，用于实现丰富的 PDF 打印功能。目前，该库支持 C/C++ 和 C# 两种主流开发语言，方便开发者在 Windows 平台上集成 PDF 打印功能。
API 文档与 Demo
- API 文档目录：位于
foxitpdfsdk_xxx_win\doc\PrintManager目录下，详细描述了PDFPrintManager的各项功能及其 API 使用方法。 - Demo 目录：位于
foxitpdfsdk_xxx_win\examples\extensions_demo\printmanager目录下，提供了使用PDFPrintManager的示例代码，方便开发者快速上手。
功能特性
PDFPrintManager 提供了以下核心功能：
- 获取打印机信息：能够列出系统上已安装的打印机名称及其属性。
- 设置打印参数：支持设置打印参数，如纸张大小、打印质量、打印份数等。
- 启动与取消打印任务：能够启动打印任务，并在需要时取消正在进行的打印任务。
- 获取打印状态：实时获取打印任务的执行状态，如正在打印、打印完成、打印取消等。
其他开发语言使用
对于非 C/C++ 和 C# 的开发语言，开发者可以通过调用 C 接口的方式来实现对 PDFPrintManager 的使用。例如，Java 开发者可以通过 JNI（Java Native Interface）技术来调用 C/C++ 动态链接库（DLL）中的函数。
Java 示例
这里提供一个简单的 Java 示例，用于说明如何通过 JNI 调用 C/C++ 动态链接库中的函数来使用 PDFPrintManager。请注意，具体的实现细节和代码需要根据实际的库函数和 JNI 规则进行编写。
1.下载JNA: Central Repository: net/java/dev/jna/jna (maven.org)
2.在IDEA中导入jna。
2.添加将导入C++接口的java文件：PrintManager_c.java 拷贝到项目里。
代码如下：
import com.sun.jna.Native;
import com.sun.jna.Library;
import com.sun.jna.NativeLong;
import com.sun.jna.Structure;
//import com.sun.jn;
public interface PrintManager_c extends Library {
PrintManager_c mydll = (PrintManager_c)Native.load(
"D:\\下载\\foxitpdfsdk_8_4_1_win\\lib\\fsdk_printmanager_win64.dll",PrintManager_c.class);

int FXPM_GetJobCollate(int managerID, int jobID);
String FXPM_GetJobPrinter(int managerID, int jobID);
int FXPM_IsJobAutoCenter(int managerID, int jobID);
}
3.如果是x64的环境，请修改PrintManager_c.java中fsdk_printmanager_win64.dll的路径
fsdk_printmanager_win64.dll文件在C++版本的Foxit PDF SDK开发包的lib目录中，请确保对应的fsdk_win64.dll和fsdk_printmanager_win64.dll处于同一目录下
4. 打印PDF，参考test_print.java中的代码。

程序运行时需要键入选择打印机和要打印的PDF文件路径。
(纸张尺寸、缩放等可以参考代码里注释掉的那部分参数设置)
