DUPLEX

Specifies whether printing is to be done on both sides of each sheet. If DUPLEX is not specified, the value specified in the form definition or the internal copy group is used.

You can specify the DUPLEX parameter in an OUTPUT statement, as follows:

DUPLEX=NO | NORMAL | TUMBLE

The values are:

NO

Specifies the printing is to be done on only the front side of each sheet.

NORMAL

Specifies printing is to be done on both sides of the sheet, after which the sheets can be bound on the long edge of the paper.

TUMBLE

Specifies printing is to be done on both sides of the sheet, after which the sheets can be bound on the short edge of the paper.

See Specifying duplex printing for examples of using the DUPLEX parameter. For more information about duplex printing, see Duplex printing.
