Thank you for your post.
A few users have encountered the same problem, and we cannot determine what is the cause. This only seems to occur on Windows printers, so I'm assuming you are using Windows (Several of these users are currently using Windows Vista).
We are still trying to find the cause, so if you can remember anything that has changed over the past few days, it could be helpful to us.
In the meantime, use a script to print (as this work fine).
