I am having a similar problems. Everything looks perfect on the screen. When it prints on the red form, everything is about 0.5 cm to the left. I am running Adobe Reader 11.0.07 and it says that no updates are available. I am printing at Actual Size. I have checked and unchecked "Choose paper source PDF page size." There is no difference between the two when printing. My print preview looks the same as yours- with no red background. 
I did not have this problem with the last version of the form and I am using the same computer and printer.
