Java實現(xiàn)打印功能.doc

Java實現(xiàn)打印功能用java實現(xiàn)打印，java.awt中提供了一些打印的API,要實現(xiàn)打印，首先要獲得打印對象，然后繼承Printable實現(xiàn)接口方法print，以便打印機進行打印，最后用用Graphics2D直接輸出直接輸出。下面代碼實現(xiàn)了簡單的打印功能：importjava.awt.BasicStroke;importjava.awt.Color;importjava.awt.Component;importjava.awt.Font;importjava.awt.Graphics;importjava.awt.Graphics2D;importjava.awt.Image;importjava.awt.Toolkit;importjava.awt.RenderingHints;importjava.awt.font.FontRenderContext;importjava.awt.font.LineBreakMeasurer;importjava.awt.font.TextAttribute;importjava.awt.font.TextLayout;importjava.awt.geom.Point2D;importjava.awt.image.BufferedImage;importjava.awt.print.Book;importjava.awt.print.PageFormat;importjava.awt.print.Paper;importjava.awt.print.Printable;importjava.awt.print.PrinterException;importjava.awt.print.PrinterJob;importjava.text.AttributedString;importjavax.swing.JApplet;publicclassPrintTestimplementsPrintable/*paramGraphic指明打印的圖形環(huán)境*paramPageFormat指明打印頁格式（頁面大小以點為計量單位，1點為1英才的1/72，1英寸為25.4毫米。A4紙大致為595842點）*parampageIndex指明頁號*/publicintprint(Graphicsgra,PageFormatpf,intpageIndex)throwsPrinterExceptionSystem.out.println(pageIndex=+pageIndex);Componentc=null;/printstringStringstr=中華民族是勤勞、勇敢和富有智慧的偉大民族。;/轉(zhuǎn)換成Graphics2DGraphics2Dg2=(Graphics2D)gra;/設置打印顏色為黑色g2.setColor(Color.black);/打印起點坐標doublex=pf.getImageableX();doubley=pf.getImageableY();switch(pageIndex)case0:/設置打印字體（字體名稱、樣式和點大?。ㄗ煮w名稱可以是物理或者邏輯名稱）/Java平臺所定義的五種字體系列：Serif、SansSerif、Monospaced、Dialog和DialogInputFontfont=newFont(新宋體,Font.PLAIN,9);g2.setFont(font);/設置字體/BasicStrokebs_3=newBasicStroke(0.5f);floatdash1=2.0f;/設置打印線的屬性。/1.線寬2、3、不知道，4、空白的寬度，5、虛線的寬度，6、偏移量g2.setStroke(newBasicStroke(0.5f,BasicStroke.CAP_BUTT,BasicStroke.JOIN_MITER,2.0f,dash1,0.0f);/g2.setStroke(bs_3);/設置線寬floatheigth=font.getSize2D();/字體高度System.out.println(x=+x);/-1-用Graphics2D直接輸出/首字符的基線(右下部)位于用戶空間中的(x,y)位置處/g2.drawLine(10,10,200,300);Imagesrc=Toolkit.getDefaultToolkit().getImage(D:EclipseWorkSpace3.1Kfc-wuxiWebRootimageKFC.jpg);g2.drawImage(src,(int)x,(int)y,c);intimg_Height=src.getHeight(c);intimg_width=src.getWidth(c);/System.out.println(img_Height=+img_Height+img_width=+img_width);g2.drawString(str,(float)x,(float)y+1*heigth+img_Height);g2.drawLine(int)x,(int)(y+1*heigth+img_Height+10),(int)x+200,(int)(y+1*heigth+img_Height+10);g2.drawImage(src,(int)x,(int)(y+1*heigth+img_Height+11),c);returnPAGE_EXISTS;default:returnNO_SUCH_PAGE;publicstaticvoidmain(Stringargs)/通俗理解就是書、文檔Bookbook=newBook();/設置成豎打PageFormatpf=newPageFormat();pf.setOrientation(PageFormat.PORTRAIT);/通過Paper設置頁面的空白邊距和可打印區(qū)域。必須與實際打印紙張大小相符。Paperp=newPaper();p.setSize(590,840);/紙張大小p.setImageableArea(10,10,590,840);/A4(595X842)設置打印區(qū)域，其實0，0應該是72，72，因為A4紙的默認X,Y邊距是72pf.setPaper(p);/把PageFormat和Printable添加到書中，組成一個頁面book.append(newPrintTest(),pf);/獲取打印服務對象PrinterJobjob=PrinterJob.getPrinterJob();/設置打印類job.setPageable(book);try/可以用printDialog顯示打印對話框，在用戶確認后打??；也可以直接打印/booleana=job.printDialog();/if(a)/job.print();/catch(PrinterExceptione)e.printStackTrace();這個例子實現(xiàn)了打印字符串，線（包括虛線）和打印圖片。而且通過Paper的setImageableArea可以設置打印的區(qū)域和邊距，讓開發(fā)者隨意的設置打印的位置。下面的打印代碼沒有設置打印區(qū)域，默認為打印紙張的區(qū)域和邊距，比如我們一般用的A4紙，打印的起點X和Y坐標則是72，72。無區(qū)域設置的代碼：importjava.awt.BasicStroke;importjava.awt.Color;importjava.awt.Component;importjava.awt.Font;importjava.awt.Graphics;importjava.awt.Graphics2D;importjava.awt.Image;importjava.awt.Toolkit;importjava.awt.RenderingHints;importjava.awt.font.FontRenderContext;importjava.awt.font.LineBreakMeasurer;importjava.awt.font.TextAttribute;importjava.awt.font.TextLayout;importjava.awt.geom.Point2D;importjava.awt.image.BufferedImage;importjava.awt.print.Book;importjava.awt.print.PageFormat;importjava.awt.print.Paper;importjava.awt.print.Printable;importjava.awt.print.PrinterException;importjava.awt.print.PrinterJob;importjava.text.AttributedString;importjavax.swing.JApplet;publicclassPrintTest1implementsPrintable/*paramGraphic指明打印的圖形環(huán)境*paramPageFormat指明打印頁格式（頁面大小以點為計量單位，1點為1英才的1/72，1英寸為25.4毫米。A4紙大致為595842點）*parampageIndex指明頁號*/publicintprint(Graphicsgra,PageFormatpf,intpageIndex)throwsPrinterExceptionSystem.out.println(pageIndex=+pageIndex);Componentc=null;/printstringStringstr=中華民族是勤勞、勇敢和富有智慧的偉大民族。;/轉(zhuǎn)換成Graphics2DGraphics2Dg2=(Graphics2D)gra;/設置打印顏色為黑色g2.setColor(Color.black);/*Paperpaper=pf.getPaper();/得到頁面格式的紙張paper.setSize(500,500);/紙張大小paper.setImageableArea(0,0,500,500);/設置打印區(qū)域的大小System.out.println(paper.getWidth();System.out.println(paper.getHeight();pf.setPaper(paper);/將該紙張作為格式*/打印起點坐標doublex=pf.getImageableX();doubley=pf.getImageableY();switch(pageIndex)case0:/設置打印字體（字體名稱、樣式和點大?。ㄗ煮w名稱可以是物理或者邏輯名稱）/Java平臺所定義的五種字體系列：Serif、SansSerif、Monospaced、Dialog和DialogInputFontfont=newFont(新宋體,Font.PLAIN,9);g2.setFont(font);/設置字體/BasicStrokebs_3=newBasicStroke(0.5f);floatdash1=4.0f;g2.setStroke(newBasicStroke(0.5f,BasicStroke.CAP_BUTT,BasicStroke.JOIN_MITER,4.0f,dash1,0.0f);floatheigth=font.getSize2D();/字體高度System.out.println(x=+x);/使用抗鋸齒模式完成文本呈現(xiàn)/*g2.setRenderingHint(RenderingHints.KEY_TEXT_ANTIALIASING,RenderingHints.VALUE_TEXT_ANTIALIAS_ON)
