2.printer class

    import java.awt.component;     import java.awt.dimension;     import java.awt.graphics;     import java.awt.graphics2d;     import java.awt.print.pageformat;     import java.awt.print.printable;     import java.awt.print.printerexception;      public class printer implements printable {     final component comp;      public printer(component comp){         this.comp = comp;     }      @override     public int print(graphics g, pageformat format, int page_index)              throws printerexception {         if (page_index > 0) {             return printable.no_such_page;         }             // bounds of component         dimension dim = comp.getsize();         double cheight = dim.getheight();         double cwidth = dim.getwidth();             // bounds of printable area         double pheight = format.getimageableheight();         double pwidth = format.getimageablewidth();             double pxstart = format.getimageablex();         double pystart = format.getimageabley();             double xratio = pwidth / cwidth;         double yratio = pheight / cheight;         graphics2d g2 = (graphics2d) g;         g2.translate(pxstart, pystart);         g2.scale(xratio, yratio);         comp.paint(g2);             return printable.page_exists;     }        }
