Thanks Peter. Actually the Service running under the system account. I have set up an account for the service. this account has administrative priviledges. now the application identifies the printer. since i have created a bat file and execute now it doesn't print because the user account doesnot have priviledges to the killing of the process. please find the code attached FileWriter fw =new FileWriter(PDFPath+"printPDF.bat"); PrintWriter out = new PrintWriter(fw); out.println("taskkill/IM AcroRd32.exe /t"); out.println("CALL START /MIN AcroRd32.exe /h /p "+PDFPath+filename); out.close(); fw.close(); String batPath = PDFPath + "printPDF.bat"; tr = Runtime.getRuntime(); Process p = tr.exec(batPath); any ideas.
