First of all, my english is not good, sorry.

I´ve visited most of pages you post, but I don´t want graphic print, and the other ones are a few hards for me...

I want modify my little code to configure margins, copies and orientation, and is a pain for me, because I´m not a java developper.

If I can´t do it with little modifications, then this is not valid for me, and I soud find one other method to do.

Really Thanks everybody. Could you help me more ???

THX....

>How can I change orientation document (landscape, portrait) ??
You can do when you open the Printer page

>How can I change margins ??
You could set the attribute of your Doc object

>How can I print more than one copy ??
You can do when you open the Printer page

I am really confuse... Java is not my "native language"...

Giant2, can you explain on my code your comments ??

>>How can I change orientation document (landscape, portrait) ??
>You can do when you open the Printer page

>>How can I print more than one copy ??
>You can do when you open the Printer page

over your PrintJob object you can call these methods:
printDialog()
and
printDialog(PrintRequestAttributeSet attributes)
The first open a printer page where you can specify the orientation and other attribute.
The second open a printer page, as previous, but you can pass it your default attribute.

>>How can I change margins ??
>You could set the attribute of your Doc object

I see you have an object called p for the properties. You can specify it.

p object ??
I don´t have a p object for the properties...
this object is form Naeemg code, but is too complicated for me....

:)

Oh, damn

the solution don´t work with text.

I finally reach print an image in landscape mode, but if I try to print a text file, the orientation don´t change.


The code is the same, but if I try to print a file I write:

InputStream is = new BufferedInputStream(
                new FileInputStream("c:\\file.txt"));

            // Find the default service
            DocFlavor flavor = DocFlavor.INPUT_STREAM.AUTOSENSE;


And if I try to print an Image I write:
InputStream is = new BufferedInputStream(
                new FileInputStream("c:\\image.gif"));

            // Find the default service
            DocFlavor flavor = DocFlavor.INPUT_STREAM.GIF;



In the file case I tried to change the AUTOSENSE by other things, but don´t work. A sun.print.PrintJobFlavorException: invalid flavor is trhow.

see here for options you can use:
http://java.sun.com/j2se/1.4.2/docs/api/javax/print/DocFlavor.INPUT_STREAM.html

I tried all options, but no success.
