Did you ever solve this? We're using ArchiCAD v11 and Mac OS 10.5.7 and had the same problem.
Here's the solution, at least for us. We use 2 monitors -the laptop monitor and a second screen. If you try to print a layout from whichever monitor is the secondary monitor (for us it was the laptop screen), the preferences in the archicad menu in the print screen will be blank. If you move the layout to the primary screen and try to print, everything will be fine.
Crazy, huh? I'm very impressed with the coworker who figured this out; turns out he was printing layouts from both screens, so things worked half the time. And our computer guy kept yelling at him "you must be doing something different!" Turns out he was.
