Setup

When we talk about page size, we’re talking about the page size you’ve defined for your publication. This page size should be the same as the page size of the printed piece you intend to produce. “Paper size,” on the other hand, is the size of the medium you’re printing on. The Setup pane of the Print dialog box lets you specify paper size, as well as how you want the page to appear on that paper (see Figure 11-3).

Paper Size

PPDs contain information about the paper sizes that a printer can handle, and this information then shows up in the Paper Size pop-up menu. When you specify a non-PostScript printer, Paper Size changes to Defined by Driver, and you’ll have to handle the paper size in the printer driver dialog box. Once again, the paper size doesn’t have to be the same as your page size; if you’re printing page marks (like crop marks), then the paper size will need to be larger. In the case of printers that image larger sheets of film, we usually set Paper Size to Custom, and then leave the Width and Height fields set to Auto (so InDesign figures out the proper imaging area for us).
