java - File opens before printing? -

-

hi m using program print files bt opens file before printing?i want remove that.any suggestions?

import java.awt.desktop; import java.io.file; import java.io.ioexception;  public class printfile {        public static void filetoprint(file fis) {     try {       desktop desktop = null;       if (desktop.isdesktopsupported())       {          desktop = desktop.getdesktop();          }           desktop.print(fis);          system.out.print("printing document");     }     catch (ioexception ioe)     {       ioe.printstacktrace();     }    } }

the desktop api in awt uses native functionality of system (in case windows.) jvm invoking shellexecute/shellexecuteex on file "print" command. way windows handles command search registry file type's print command, , run that. file types, result in application handles opening, , executing print command automatically.

in short, don't think you'll able use desktop api without having applications open. need printing (which, of course, difficult.)
