I just tried a HP Officejet (installed following this guide: http://how-to.wikia.com/wiki/How_to_get_an_HP_OfficeJet_scanner_to_work_in_Linux.
It scans, but I specificly want to take advantage of the duplex scanning option of this multifunctional thing.
options chosen in de "scan document" dialog:
page options tab: "double sided" (side facing) and scan all pages.
scan options tab:
batch: both yes and no tried
source: auto/adf tried.
I don't see what option I overlook?
thanks in advance!
