Maps in driving directions are missing (but checked in options)

Even I checked “Maps in driving directions” under options, they are not printed out. I’ve only got blank boxes on the printout.
I tried several browsers (Safari, Chrome, Firefox on Mac OS 10.10. and Safari on Windows 8.1), the behavior is everywhere the same. 

We’ve pushed an update to solve this problem. It will be in effect within the hour.
