I have long been a fan of two-sided printing in printers to save trees. When I installed Panther, it effectively killed my ability to use the Duplex unit in my HP 990cse printer. Besides, I wanted a better Photo Printer, so I got a Canon i960 with a Duplex unit and gave away my HP 990cse. Duplex printing in Jaguar with the old HP 990cse worked the way it should. The first page would print right side up, top to bottom, the page would pause for ink to set then it was sucked back into the Duplex unit and the bottom back surface would then start to print upside down, bottom to top. So, the finished document would have both odd and even numbered pages correctly oriented. With my new Canon, it works mechanically the same as the HP 990cse but the driver software is screwed up. I installed the Canon drivers on top of the Panther installation. Like the HP, it prints the first page right side up, top to bottom. It pauses then pulls the page back into the Duplex unit and presents the bottom reverse side of the page for printing. But instead of printing upside down, bottom to top it prints the second side the same as the first: right side up, top to bottom. Therefore, documents printed with the Duplex printing have odd numbered pages facing right side up and the even numbered pages upside down. Does anyone know of a workaround for this? Is it the fault of Panther or the Canon drivers? jg
