Printing on Custom Size Paper

Use the following procedure to register a custom paper size (and specify margins if necessary).

Open the document that you want to print.
Select [Page Setup] on the [File] menu.
Click the [Printer:] pop-up menu, and select this printer.
Open the dialog box for registering a custom paper size.
Click [Paper Size] in the pop-up menu, and then select [Manage Custom Size...].
Click [New] or [], and then enter a name for the custom paper size.
If you are modifying an existing custom paper size, click the setting name.
You can register multiple custom paper sizes.
Enter the dimensions of the custom paper size in the [Width], [Height], and [Length] boxes, and then enter the margin dimensions in [Top], [Bottom], [Left], and [Right].
If "cm" is selected in [Units], the actual setting may differ slightly from the entered value.
Click [OK].
Print the document using the print function in the document's native application.

Under some versions of Mac OS, custom size paper cannot be registered unless “Printer Default” is specified as the destination.
Due to approximation, the actual dimensions of custom size paper might differ slightly from the value entered by the user.
