try a short demo sketch - just the initialization of the display and one single "print".
Does it work?
If not - post this example sketch in code tags so we can check it.
Additionally - please note which ESP core Version have you installed.
P.S.: some time ago I made a Library for HT16K33 based displays. It provides the common "print" interface. You might give it a try:
