I'm wondering if there is some trick to power my OctoPi with the power supply of my 3D printer. I'm using an Geeetech I3 Pro W.

The power supply itself should be able, but the output is AFIK volt. Not my desired 5V for USB. it would be a shame if I really would need to buy a new power supply when I have a strong one actually running. My current power supply causes a lot of "Under-votage detected!" warnings.

After thinking a little about the specs there are cigarette lighter adapter for cars they use 12V. Has anyone experience with using that on his printer?

Where are you plugging in the USB power to the Pi? If you are back powering it from the data connection, you will bypass the fuses and potentially ruin your Pi or worse. Look at this wiki under the power section.

As far as powering the Pi through a 12 V to 5 V converter this will work as long as the current is rated above what the Pi will use, preferably a lot higher. You will also have to consider how this option will cut the power abruptly when you switch the printer off and the Pi will not boot down properly.

What you are looking for is called a "buck converter" or a "step down module". These literally cost about half a buck/Euro a piece. These converters convert a high voltage into a low voltage, the better ones are able to draw 2 to 3 Amps, which is required for stable operation of the Raspberry Pi.

If you have an old computer power supply of a decent brand (probably not as you refer to a kit/assembled printer, but added for completeness), you can even use the standby 5 V line out and switch the power supply on using a relay to short the green wire of the PSU to ground. This is how I use it on one of my printers.

Note to power the Raspberry Pi through the mini USB port, to not bypass safety features.
