PAGRTT = *DEVD

If PAGRTT = *DEVD, then the following are true:

If the output is too large to fit on the form, computer output reduction is performed automatically.
If the page is wider than it is long, the page is rotated 90 degrees. If it is not wider than it is long, the page is not rotated.
For computer output reduction printing, the PRTQLTY (print quality) parameter value must be either *DRAFT or *DEVD. If the PRTQLTY parameter value is *STD or *NLQ, spooled files are printed without computer output reduction (COR) and without page rotation.
When using the PAGRTT parameter, do not specify *DEVD for the FONT parameter value. When FONT(*DEVD) is used, the system cannot determine the exact page width; therefore, page positioning might not be as intended.

Note:

When the PAGRTT parameter value is *AUTO or *DEVD, computer output reduction (COR) is not provided if the spooled file has any of the Device Requirements fields set to Y. Use the Work with Spooled Files (WRKSPLF) command and select option 8=Attributes to view the device requirements for any spooled file.
