Both side printing [OpenOffice.org/LibreOffice]

That setting is made in the Printer Properties. All you need do in / File / Print window is press the Properties button beside the Printer name and select Duplex or Double sided printing. OpenOffice will send a stream of pages to the printer, which will print 1/2, 3/4 etc. You can also set the installed Printer at system level always to print Duplex.
