Paper Handling
Page order
You can choose to print your document in the normal page order (1,2,3...) or reverse order (...3,2,1).
This option allows you to choose whether to print only odd or even number of pages. This is useful if you are using manual duplex for which you first print all odd pages,
Destination paper size
Scale documents to fit on the size of paper in your printer. For example, you can take a document formatted for A3 and print it on A4 paper using an A4 printer.
