A: Hi Hamood,
Thank you for submitting this question.
In response to your query, I would advise that unfortunately, the Samsung C1860FW only supports manual duplex printing, not automatic.
However, you may wish to take a look at the Samsung CLX-6260FW which features an automatic duplex function for print, copy and scan as standatrd: http://www.printerbase.co.uk/samsung-clx-6260fw-a4-colour-laser-mfp-with-fax-and-wi-fi.html?
Please let us know if you require any further information in relation to this or any other queries that you may have.
