When none of the standard media sizes in a device PPD file fit a job's needs, you can use a custom size, if supported by the PPD.
Note: In PPD files, the media size is referred to as the device PageSize.

1. In the Media list, right-click the media resource, and select Edit.
2. In the Media Configuration dialog box, click Custom Size.
   This button is available only if the device PPD supports custom media sizes.
3. Choose a task:
• To add a new media size, click Add, give the new size a name, and specify its dimensions and orientation.
• To change an existing custom media size, select the size name, click Edit, and edit the dimensions, name, and orientation, as needed.
• To delete an existing custom media size, select the size name, and click Delete. You cannot delete a standard size.
  Note: Standard sizes that are defined in the PPD files cannot be edited or deleted.
4. Click OK as needed to apply your changes and return to the Media Configuration dialog box.
   The Size list contains your changes.
5. Choose one of the following steps:
   • Select the new size for this media resource, and close the dialog box.
   • Do not select the new size. Close the dialog box, right-click the same item in the Media list, and select Add. You can then create a new media resource with a new nickname for your new custom size.

You can now use the custom media for a press run. The grip edge appears at the bottom of the workspace, according to the orientation that you specified.
