Details

When DUPLEX is on, the driver sets up the printer for duplex operation. Before producing the first graph, set GSFMODE=REPLACE on the GOPTIONS statement, and DUPLEX on an OPTIONS or GOPTIONS statement. You can also use the BINDING= option in conjunction with DUPLEX. Before producing the second graph, set GSFMODE=APPEND on the GOPTIONS statement so that the driver knows to place succeeding graphs on the next available side of paper.

If DUPLEX is in effect, the page's inside (binding) margin is set equal to the current HORIGIN setting, and the outside margin is set equal to

XMAX - HSIZE - HORIGIN
In terms of even- and odd-numbered pages, this means the following:

odd-numbered pages HORIGIN determines the left margin, and XMAX-HSIZE-HORIGIN determines the right margin

even-numbered pages XMAX-HSIZE-HORIGIN determines the left margin, and HORIGIN determines the right margin

For PostScript printers, if you do not use the PPDFILE= option to specify a PPD (PostScript Printer Description) file, a generic PostScript Level 1 duplex command is added to the driver output. If PPDFILE= is used, the duplex command is obtained from the PPD file.
