我创建了一个java applet,用于将文本文件内容从远程位置复制到本地计算机。它工作正常,并尝试使用DOS命令(Windows XP)进行打印。它不起作用,但它在Ubuntu OS中运行良好。你能帮我改进我的代码吗?
这是我的代码
try {
String server=this.getParameter("SERVER");
String filename=this.getParameter("FILENAME");
String osname=System.getProperty("os.name");
String filePath="";
URL url = new URL("http://10.162.26.8/openLypsaa/reports/report_oc/127.0.0.1_sys_ANN_milkbill");
URLConnection connection = url.openConnection();
InputStream is = connection.getInputStream();
if("Linux".equals(osname))
{
filePath = "/tmp/OLFile";
}
else
{
filePath = "C:/WINDOWS/Temp/OLFile";
}
OutputStream output = new FileOutputStream(filePath);
byte[] buffer = new byte[256];
int bytesRead = 0;
while ((bytesRead = is.read(buffer)) != -1)
{
System.out.println(bytesRead);
output.write(buffer, 0, bytesRead);
}
output.close();
if("Linux".equals(osname))
Runtime.getRuntime().exec("lp /tmp/OLFile").waitFor();
else
Runtime.getRuntime().exec("print C:/WINDOWS/Temp/OLFile").waitFor();
}

在Windows中,您希望使用:filePath = "C:\\WINDOWS\\Temp\\OLFile";
和
Runtime.getRuntime().exec("print C:\\WINDOWS\\Temp\\OLFile").waitFor();
您还可以谷歌了解PathSeparator

您可以使用可在每个平台上使用的java打印服务。此代码段将您的打印件发送到默认打印机。
public static void main(String[] args) {
FileInputStream textStream;
try
{
textStream = new FileInputStream("D:\\email_addresses.txt");
DocFlavor myFormat = DocFlavor.INPUT_STREAM.AUTOSENSE;
Doc myDoc = new SimpleDoc(textStream, myFormat, null);
PrintRequestAttributeSet aset = new HashPrintRequestAttributeSet();
aset.add(new Copies(1));
aset.add(Sides.ONE_SIDED);
PrintService printService = PrintServiceLookup.lookupDefaultPrintService();
System.out.println("Printing to default printer: " + printService.getName());
DocPrintJob job = printService.createPrintJob();
job.print(myDoc, aset);
} catch (FileNotFoundException e1) {
e1.printStackTrace();
} catch (PrintException e) {
e.printStackTrace();
}
}
