DocPrintJob job = service.createPrintJob(); //創建列印作業 FileInputStream fis = new FileInputStream(file); //構造待列印的文件流 DocAttributeSet das = new HashDocAttributeSet();
Doc doc = new SimpleDoc(fis, flavor, das);
job.print(doc, pras);
} catch (Exception e) {
e.printStackTrace();
}
}
}
}
}

❷ java怎麼實現列印機列印

javax.print***
可以 當圖形那樣打開，挺費勁的
想列印好看、又省事，一般是轉專pdf等有格式的文檔來列印

❸ 怎麼用java調用默認列印機列印文檔

java實現調用默認列印機列印文檔（以D盤.txt文檔為例），代碼如下：

importjava.io.File;
importjava.io.FileInputStream;
importjava.io.FileNotFoundException;
importjavax.print.Doc;
importjavax.print.DocFlavor;
importjavax.print.DocPrintJob;
importjavax.print.PrintException;
importjavax.print.PrintService;
importjavax.print.PrintServiceLookup;
importjavax.print.ServiceUI;
importjavax.print.SimpleDoc;
importjavax.print.attribute.DocAttributeSet;
importjavax.print.attribute.HashDocAttributeSet;
importjavax.print.attribute.HashPrintRequestAttributeSet;
importjavax.print.attribute.PrintRequestAttributeSet;
/**

publicclassPrintDemoII{
publicstaticvoidmain(String[]args){
DocFlavorflavor=DocFlavor.INPUT_STREAM.AUTOSENSE;
PrintRequestAttributeSetaset=();
PrintService[]pservices=PrintServiceLookup.lookupPrintServices(flavor,aset);
PrintServicedefaultService=PrintServiceLookup.lookupDefaultPrintService();
PrintServiceservice=ServiceUI.printDialog(null,200,200,pservices,
defaultService,flavor,aset);
if(service!=null){
try{
DocPrintJobpj=service.createPrintJob();
FileInputStreamfis=newFileInputStream("D:"+File.separator+".txt");//列印D盤.txt文檔。
DocAttributeSetdas=newHashDocAttributeSet();
Docdoc=newSimpleDoc(fis,flavor,das);
pj.print(doc,aset);
}catch(FileNotFoundExceptionfe){
fe.printStackTrace();
}catch(PrintExceptione){
e.printStackTrace();
}
}else{
System.out.println("列印失敗");
}
}
}

❹ Java如何調用系統列印機列印文件

具體步驟如下：

import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.io.InputStream;

import javax.print.Doc;
import javax.print.DocFlavor;
import javax.print.DocPrintJob;
import javax.print.PrintService;
import javax.print.PrintServiceLookup;
import javax.print.SimpleDoc;
import javax.print.attribute.DocAttributeSet;
import javax.print.attribute.HashDocAttributeSet;
import javax.print.attribute.HashPrintRequestAttributeSet;
import javax.swing.JFileChooser;

public class PrintDemo {

public static void main(String[] args) {
JFileChooser fileChooser = new JFileChooser(); // 創建列印作業
File file = new File("f:/111.txt"); // 獲取選擇的文件
// 構建列印請求屬性集
HashPrintRequestAttributeSet pras = new HashPrintRequestAttributeSet();
// 設置列印格式，因為未確定類型，所以選擇autosense
DocFlavor flavor = DocFlavor.INPUT_STREAM.AUTOSENSE;
// 定位默認的列印服務
PrintService defaultService = PrintServiceLookup.lookupDefaultPrintService();
InputStream fis = null;
try {
DocPrintJob job = defaultService.createPrintJob(); // 創建列印作業
fis = new FileInputStream(file); // 構造待列印的文件流
DocAttributeSet das = new HashDocAttributeSet();
Doc doc = new SimpleDoc(fis, flavor, das);
job.print(doc, pras);
} catch (Exception e) {
e.printStackTrace();
} finally {
if (fis != null) {
try {
fis.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
}

❺ java 列印機實現(急)

這個很明顯是使用讀取文件流來實現列印
所以沒有GUI界面
也可以實現
只要載入文件的路徑就可以了
