Switching between printers
If you have more than one printer available, you can select which you want to
use. The printer you select is called the default printer. All your documents
will be printed on the default printer until you select a new one.
To change the default printer, use one of these four methods, as described in
the next sections.
m Drag the document you want to print to a desktop printer icon, and it will
automatically become the default printer.
m Select the desktop printer icon and use the Printing menu to set the printer
as the default.
m Select a new printer using the Chooser.
m Select a new printer using the Printer icon in the desktop menu.
Note: Switching between printers may change how much information you
can fit on a page. It’s best to choose a printer before you spend much time
formatting the document.
Drag the document you want to print to a desktop printer icon
Drag the icon of any document you want to print to the icon of the printer
you want to use. (See “Printing With a Desktop Printer,” earlier in this
chapter.)
Printing PostScript files as text
To print a PostScript file as text, hold down the Option key and drag the
document to the icon of the printer you want to use.
