Most people print from the Web by clicking the print button that appears on most browser windows.
This is a perfectly acceptable method to use in most circumstances. However, there are times, such as now, when you might want to change one or more of the printer settings for a Web page. Choose Print from the File menu. You should see a dialog box that looks similar to those you have seen when printing from other programs. You should see some printing choices including radio buttons that will let you select portrait or landscape positioning for your printer.
