each frame individually. Tip The Print Frames options are available only if the Web site you're trying to print is using frames. To quickly determine whether a page is using frames, and thus whether you can use the print by frame method, right-click any-where on the page. If the contextual menu includes a This Frame option, as shown in Figure 12-8, the page is using frames.   Figure 12-8: If the Web site's contextual menu has a This Frame submenu, the site uses frames, and you can use the print-by-frame method. New Web design techniques are making frames obsolete, so you will see fewer and fewer Web sites using them as time goes by. Some Web sites that appear to be using frames might actually be using a newer technique instead. Printing multiple copies of a page By default, Firefox prints a single copy of a Web site, but you can print as many copies as you need. This feature comes in handy if, for example, you need to pass out a copy of the Web site to everyone on your team at work. To print multiple copies of a Web site, follow these steps: Open the Print window. I provide instructions for doing so a bit earlier in this part of the chapter. Under Copies, enter the number of copies you want to print. If you want to print the copies in a collated fashion, select the Collate check box. Collation affects only multipaged print jobs. By default, Firefox prints all the copies of each page in a multipaged Web site in order. For example, if you're printing five copies of a three-paged Web site, Firefox prints five copies of page 1, then five copies of page 2, and finally five copies of page 3. If you collate the copies, Firefox prints entire copies of the Web site at a time. In this example, Firefox prints page 1, then page 2, then page 3, and repeats that five times. Figures 12-9 and 12-10 illustrate the difference between non-collated and collated printing. Collation is handy because when all copies finish printing, they're already in sets. Without collation, you have to reconstruct each copy of the Web site manually. Figure 12-9: Without collated printing, Firefox prints all the copies of page 1, then all the copies of page 2, and so on Figure 12-10: but with collated printing, Firefox prints each complete set one at a time. Click Print to print the indicated number of copies. Tip If you plan to print a lot of pages in black and white, you might want to consider buying a laser printer. Although they're more expensive than traditional ink jet printers, they print much more quickly. Changing page size and other printer-specific options Many printers offer additional formatting options beyond those offered by Firefox, which I discuss in this chapter. For example, certain printers allow you to specify different paper sizes or qualities and automatically optimize printing for those conditions. The best way to determine what your printer supports is to consult its manual or simply to look in the Print window and see. (In Windows, you might need to click a Properties button in the window to access the printer-specific options.) I provide instructions for opening the Print window earlier in this chapter.
