Open document data using the application software. From the [File] menu, select [Page Setup].
Check that the desired printer is selected in [Format for:].
The [Page Attributes] window appears.
In [Page Attributes], you can configure basic settings about paper.
| Settings | Description | 
|---|---|
| [Paper Size:] | Select the size of paper for printing. To print on custom sized paper, use [Manage Custom Sizes...]. For details, refer to Here. | 
| [Orientation:] | Specify the orientation of the original created in application software. If the setting in the printer driver differs from the one specified in the application software, correct the setting. | 
| [Scale:] | Specify the zoom ratio to enlarge or reduce the original image. The setting range differs depending on the Mac OS version. | 

When you want to print on the entire paper of the standard size, select "W" for each standard size in [Paper Size:]. The original is printed at the center of paper larger than the original.
For example, if you want to center and print 8-1/2  11 (A4) size data on 11  17 (A3) sized paper, create data with the "8-1/2  11W" ("A4W") size, and then, using the printer driver, set [Paper Size:] to [8-1/2  11W] ([A4W]) and specify the paper tray to be used as [Paper Tray].
On this machine, load 11  17 (A3) size paper into the tray to use, and check the paper size as follows.
Select the tray in [Paper] for the copy mode. Select [Change Tray Setting] - [Wide Paper], specify [8-1/2  11W] ([A4W]) and make sure that the [Paper Size] is set to [Auto Detect] and 11  17 (A3) is displayed.
To print on custom sized paper, use the Tray1, Tray2, or Bypass Tray. In [Change Tray Setting] - [Wide Paper], select [8-1/2  11W] ([A4W]), and enter the paper size to use in [Change Size].
[Paper Size] and [Orientation] can also be specified in the Print window.
