问题描述
我有一个名为 myPrintableObject
的 Printable
类,并且打印方法以下列方式被覆盖:
I have a Printable
class named myPrintableObject
and print method is over-ridden in following manner:
public int print(Graphics g, PageFormat pf, int pageIndex) throws PrinterException
{
if(pageIndex<5)
{
pf.setOrientation(PageFormat.LANDSCAPE);
g.drawString("HELLO FRIEND",100,180);
return PAGE_EXISTS;
}
else
{return NO_SUCH_PAGE;}
}
我想在同一文档中横向打印多页.除第一页外正在打印.它总是以纵向打印.
I wanted to print multiple pages in landscape orientation in same document. It is printing except the first page. It is always getting printed in portrait orientation.
我该如何解决这个问题?
How can I fix this?
推荐答案
你在这里:
PrinterJob job = PrinterJob.getPrinterJob();
PageFormat pf = job.defaultPage();
pf.setOrientation(PageFormat.LANDSCAPE);
job.setPrintable(myPrintableObject, pf);
工作示例:
public class MyPrintable implements Printable {
public int print(Graphics graphics, PageFormat pageFormat, int pageIndex) throws PrinterException {
if (pageIndex < 5) {
graphics.drawString("HELLO FRIEND", 100, 180);
return PAGE_EXISTS;
} else {
return NO_SUCH_PAGE;
}
}
public static void main(String[] args) {
PrinterJob job = PrinterJob.getPrinterJob();
PageFormat pf = job.defaultPage();
pf.setOrientation(PageFormat.LANDSCAPE);
job.setPrintable(new MyPrintable(), pf);
boolean ok = job.printDialog();
if (ok) {
try {
job.print();
} catch (PrinterException ex) {
/* The job did not successfully complete */
}
}
}
}
