Hi all,
While printing,i get the IOEXception
java.io.IOException: CreateProcess: C:\\command /c copy c:\CashPrintPage.txt lpt1 error=2
�at java.lang.ProcessImpl.create(Native Method)
�at java.lang.ProcessImpl.<init>(Unknown Source)

The Code is:
public void printFile(String fileName) {
          String strCmd="";
          if(System.getProperty("os.name").equalsIgnoreCase("Windows 98"))
          strCmd = "C:\\command";
          else
strCmd = "cmd";
String []cmd=new String[5];
cmd[0]=strCmd;
cmd [1]="/c";
cmd [2]="copy";
cmd[3]=fileName;
cmd[4]="lpt1";
try {
Process child=Runtime.getRuntime().exec(cmd);// error is shown in this line
} catch (IOException ex) {
ex.printStackTrace();

hi,
you have to leave one space after "/c " & "copy " & before newfilename " lpt1"
here your modified code
import java.io.*;
public class cmd
public static void main (String args[])
String strCmd="";
if(System.getProperty("os.name").equalsIgnoreCase("Windows 98"))
strCmd = "C:\\command";
else
strCmd = "cmd";
String []cmd=new String[5];
cmd[0]=strCmd;
cmd [1]=" ";
cmd [2]="copy ";
cmd[3]=args[0];
cmd[4]=" newfilename";
try {
Process child=Runtime.getRuntime().exec(cmd);// error is shown in this line
child.wait();
System.out.println(cmd[0]+cmd[1]+cmd[2]+cmd[3]+cmd[4]);
System.out.println("1 files copied");
catch (Exception ex) {
ex.printStackTrace();
}
