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).
Print
This option allows you to choose whether to print only odd
or even numbered pages. This is useful if you are using
manual duplex for which you first print all odd pages, re-
insert the paper in the printer and then print all even
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.
