How to get HTML field on Print Format

I am trying to fetch the HTML field on print format but unable get the HTML field data.
I have created one HTML filed i.e html_01, I tried to access the html_01 field in print format in Jinja {{doc.html_01}}

But instead of HTML value i am getting Boolean value True.

HTML fields have no data. You can try a “Text” type field.
