I need to make the title in the middle of the page when printing report

Hello;

I created report using Report Builder, I need to put the Doctype Name (in my example is Vehicle Log) in the middle of the page when printing, how? Even by changing the code, no problem, I can do this if someone tell me from where.

Below is images that explain about what I am talking:

Any help about this?
I am sure it should be possible, but need someone to guide me from where to change it in the code.
