JAVA Call System printer print string __java

With the Java implementation of printing, java.awt provides some of the printing API, to achieve printing, first to obtain the print object, and then inherit printable implementation interface method print, so that the printer to print, and finally with graphics2d direct output directly.
The following code implements a simple printing function:

     Add Pageformat and printable to the book to form a page book.append (new Printtest (), PF);      
     Get Print Service object PrinterJob job = Printerjob.getprinterjob ();
     
     Sets the Print class job.setpageable (book);

   }
}

This example implements the print string, line (including dashed lines), and prints the picture. And through the paper Setimageablearea can set the printing area and margin, let the developer arbitrarily set the location of printing.
The following print code does not set the print area, defaults to the area and margins of the printed paper, such as the A4 paper we normally use, and the print start x and y coordinates are 72, 72.
