获取打印机的名字：
// 获取打印机
public static List<String> findPrints() {
List<String> list = new ArrayList<>();
HashPrintRequestAttributeSet requestAttributeSet = new HashPrintRequestAttributeSet();
DocFlavor flavor = DocFlavor.INPUT_STREAM.AUTOSENSE;
//查找所有的可用的打印服务
PrintService[] printService = PrintServiceLookup.lookupPrintServices(flavor, requestAttributeSet);
if (printService == null || printService.length == 0) {
log.info("打印获取失败，未找到可用打印机，请检查。");
}
if (printService != null) {
for (PrintService print : printService) {
list.add(print.getName());
}
}
return list;
}

excel转换成pdf
生成excel请看下面的链接：
https://blog.youkuaiyun.com/Java_Mr_Jin/article/details/124076055?spm=1001.2014.3001.5501当然我们的excel要想打印可以转换成pdf的形式，再用上面的进行打印：
关于word转换pdf需要用到jaboc，所以在这需要先下载jaboc.jar包,链接及提取码如下：
链接: 链接: https://pan.baidu.com/s/17nLuDAYC33Yu8KvwS2J2gA
提取码: qwer
将jar包解压后
1.将Jacob.jar包复制到程序的jdk的lib文件夹下
2.将dll文件复制到jdk的bin目录下
然后在idea中引入jacob.jar包
<dependency>
<groupId>com.hynnet</groupId>
<artifactId>jacob</artifactId>
<version>1.18</version>
</dependency>在java中进行实现excel转换成pdf：
package com.sangeng.controller;
import com.jacob.activeX.ActiveXComponent;
import com.jacob.com.ComThread;
import com.jacob.com.Dispatch;
import com.jacob.com.Variant;
import java.io.File;
public class DYPdfController {
//word转化pdf，传入转换前的文件路径（例："E:\\a.docx"）和转换后的文件路径（例："E:\\a.pdf"）
public static void main(String[] args) {
String sFilePath = "D:\\java-demo\\zzzzz\\qqq.doc";//文件路径
String toFilePath = "D:\\java-demo\\zzzzz\\qqq.pdf";
wordToPDF(sFilePath,toFilePath);
}
public static void wordToPDF(String sFilePath,String toFilePath) {
System.out.println("启动 Word...");
long start = System.currentTimeMillis();
ActiveXComponent app = null;
Dispatch doc = null;
try {
app = new ActiveXComponent("Word.Application");
app.setProperty("Visible", new Variant(false));
Dispatch docs = app.getProperty("Documents").toDispatch();
doc = Dispatch.call(docs, "Open", sFilePath).toDispatch();
System.out.println("打开文档:" + sFilePath);
System.out.println("转换文档到 PDF:" + toFilePath);
File tofile = new File(toFilePath);
if (tofile.exists()) {
tofile.delete();
}
Dispatch.call(doc, "SaveAs", toFilePath,17);//17是pdf格式 // FileName
long end = System.currentTimeMillis();
System.out.println("转换完成..用时：" + (end - start) + "ms.");
} catch (Exception e) {
System.out.println("========Error:文档转换失败：" + e.getMessage());
} finally {
Dispatch.call(doc, "Close", false);
System.out.println("关闭文档");
if (app != null)
app.invoke("Quit", new Variant[]{});
}
// 如果没有这句话,winword.exe进程将不会关闭
ComThread.Release();
}
}
当然转换打印完成后。记得删除生成的pdf文件：
File file=new File(toFilePath);
if(file.exists()&&file.isFile())
file.delete();
直接excel进行打印
缺点：就是不能更改打印参数
package com.sangeng.controller;
import com.jacob.activeX.ActiveXComponent;
import com.jacob.com.ComThread;
import com.jacob.com.Dispatch;
import com.jacob.com.Variant;
public class WordController {
public static void main(String[] args) {
String filePath = "E:\\a.docx";//文件路径
String printerName = "HP MFP M436 PCL6";//打印机名包含字串
printWord(filePath,printerName);
}
public static void printWord(String filePath, String printerName){
// 初始化线程
ComThread.InitSTA();
ActiveXComponent word = new ActiveXComponent("Word.Application");
//设置打印机名称
word.setProperty("ActivePrinter", new Variant(printerName));
// 这里Visible是控制文档打开后是可见还是不可见，若是静默打印，那么第三个参数就设为false就好了
Dispatch.put(word, "Visible", new Variant(false));
// 获取文档属性
Dispatch document = word.getProperty("Documents").toDispatch();
// 打开激活文挡
Dispatch doc=Dispatch.call(document, "Open", filePath).toDispatch();
//Dispatch doc = Dispatch.invoke(document, "Open", Dispatch.Method,
// new Object[] { filePath }, new int[1]).toDispatch();
try{
Dispatch.callN(doc, "PrintOut");
System.out.println("打印成功！");
}catch (Exception e){
e.printStackTrace();
System.out.println("打印失败");
}finally {
try {
if (doc != null) {
Dispatch.call(doc, "Close", new Variant(0));//word文档关闭
}
} catch (Exception e2) {
e2.printStackTrace();
}
//退出
word.invoke("Quit", new Variant[0]);
//释放资源
ComThread.Release();
ComThread.quitMainSTA();
}
}
}
导入C盘失效
文件不能直接导入c盘，因为权限问题。所以先创建一个文件夹，再导入即可
File dir=new File("C:\\nmgbzj");
File file2=new File(dir.getPath()+"/");
if(!dir.exists()){
dir.mkdir();
file2.createNewFile();
}else{
if(file2.exists()){
file2.delete();
file2.createNewFile();
}else{
file2.createNewFile();
}
}
