Checking a print preview
You can check an image of the original just as it will be printed.
When you activate this feature, PageComposer is launched before printing. Conrming how documents will
be printed this way helps prevent printing errors.
For details on print previews, see "Checking the Layout in a Preview Before Printing". (→P.357)
