Applet printing to local printer

Does anyone have sample codes for an applet that reads a file from
a server and print it out over at the user side (local printer).

The applet should be able to specify whether to print in portrait or
landscape format.

All I need is  a simple applet with one print button.
File to be printed can be hardcoded.

Thanks.

If you have the JDK 1.1 patch installed, you can print if you have enabled the UniversalPrintJobAccess privilege.

  2. (Sect. 8) How do I print from a Java program?

     [*] Use the Toolkit.getPrintJob() method

     Component c = this.getParent();
     while (c!=null && !(c instanceof Frame))
         c=c.getParent();

     PrintJob pj = getToolkit().getPrintJob((Frame) c, "test", null);
     Graphics pg = pj.getGraphics();
     printAll(pg);
     pg.dispose();
     pj.end();


     This feature was introduced with JDK 1.1. A common place to put this is
     in the code that handles a button press. Printing from an untrusted
     applet is subject to a check from the SecurityManager.

     The JDK 1.1 printing API is more a screen hardcopy facility than a full
     blown publishing and illustration hardcopy API. JDK 1.2 offers a more
     full-featured printing API.
     http://java.sun.com/printing/

     If you simply want to print text, then write it to a file and print the
     file. Or open a filename that corresponds to the printer. On Windows,
     that is "LPT1" and the code looks like:

     try {
         FileOutputStream fos = new FileOutputStream("LPT1");
         PrintStream ps = new PrintStream(fos);
                 ps.print("Your string goes here");
                 ps.print("\f");
                 ps.close();
     } catch (Exception e) {
         System.out.println("Exception occurred: " + e);
     }


     The final formfeed is needed by windows to start the printjob.

  3. (Sect. 8) What are the properties that can be used in a PrintJob? The
     properties are
        o awt.print.destination - can be "printer" or "file"
        o awt.print.printer - printer name
        o awt.print.fileName - name of the file to print
        o awt.print.numCopies - obvious
        o awt.print.options - options to pass to the print command
        o awt.print.orientation - can be "portrait" or "landscape"
        o awt.print.paperSize - can be "letter","legal","executive" or "a4"
     The defaults are destination=printer, orientation=portrait,
     paperSize=letter, and numCopies=1.

     You can search for info like this by joining the Java Developer
     Connection (it's free) at http://java.sun.com/jdc.

     and doing a search for "PrintJob".

Without going into too much detail, Netscape Communicator enables signed applets to request permission to access various system resources. It is left up to the user to grant or deny access.

An applet requests access to a system's printing resources by enabling the UniversalPrintJobAccess privilege. Once the privilege has been granted, the applet can proceed exactly as outlined above. To enable the print job privilege, you use the following code:

import netscape.security.PrivilegeManager;
import netscape.security.ForbiddenTargetException;
..
..
try {


PrivilegeManager.enablePrivilege ("UniversalPrintJobAccess");
// proceed with printing as normal
PrivilegeManager.disablePrivilege ("UniversalPrintJobAccess");


} catch (ForbiddenTargetException e) {

// user denied applet permission to access resource

}

Network printer
in windows95 you can map the port LPT1 to a network printer (-add new printer -local printer -select driver -select port (LPT1) -Install drivers ect.
-Right click...Properties ...capture printer port... -Select LPT1 then use the pass to my network printer)
in NT just share the printer on your windows NT machine. If you computer name is for example NT01 and you share your printer as PRINTER1. Now you can use the net use command for assigning the printer to the lpt1 port. for example : NET USE lpt1: \\NT01\PRINTER1 now every program that sends to the lpt1 port, will send it to \\NT01\PRINTER1
