Blank Error Box after a power failure

Hi fellows,
I was at home doing some home work brought from the office, I am encoding some reports that I will print later on. After a while, a power failure occurred, since I don't have backup power, my computer turn off. When the power was restored, I turned on the computer.
Since it was not properly shutdown, it will pass by safe mode, after a few minutes of finishing my work. I wanted to print.
In middle of the printing job an error appeared that says nothing, only the yes and no button was present.

Error
If I will select yes or no, same thing, the printing will stop. Please help me with this short ,but disturbing error.
Thanks.
