1. Click the arrow to the right of the Sheet field box to set the dimensions of a sheet of paper. You can also type the desired size directly into the Sheet box.
2. Click Edit to specify other media settings, such as weight and color mode.
3. If Substrate Catalog is supported, click the arrow to the right of the Media box to choose from the Substrate Catalog menu.
