I am trying to print an A4 folded booklet using the 'Manual Duplex' command in the Print menu, but after I have printed the first pass, and clicked on the message to turn the stack over and place it in my printer's in-tray for the second pass, the second 'Print Job' just vanishes from the queue and I'm left with my task half finished. Any ideas what might be wrong, or what I can do to get the second pass going? (Sd.) Ashvajit
