The mechanics of the print head look OK to me. The paper is properly pressed against the moving print head. So, if the dots create heat, I'd expect something on paper.

Have you applied some heat to your paper(s) by some other means? Is it possible you've got old/non-functioning paper?
Can you measure the (average) current to a dot with your voltmeter?

Thanks fo the proposals!
The paper works. I confirmed it by burning it and also by writing with a soldering iron on it. I reacts in same way as I was used to it in past.
I need to check the manual of my multimeter whether it allows averaging. Good idea, thanks!
