Using QReport D7 made a report, because in the printer to print double-sided, therefore set Deplex to true
Then print out is double, just typing is wove duplex printing (no matter choose printer Settings, turn up and down or left the same results), but with a Word of double, but normal, now USES version 4.0

But the plan is to just turn up and down to turn around, but set the duplex qreport is True, whether or not the printer choice double-sided printing or any form of double-sided printing, do double-sided printing is set by this way, seem to ignore the user's printer selected duplex printing way.
