Generating random prints with thermal printer

Hello everyone,

I have a small project there i wanted to make a randomizer which prints out a random bitmap by pressing a button.
The thermal printer is one from adafruit. Electronic wise everything is setup just the randomization is missing.

Is there a function where i can put the different bitmap print commandos in a list and the arduino picks one from it?

Thanks!

You can put bitmap pointers into an array, and index the array with your random number.

I'm sorry but can you tell me how to set up a bitmap pointer?
I tried reading through the guides but I still can't understand the syntax
