Why are bank details printing on a quote?

Hi there, @bennettplumbers.

It's possible you've entered your bank information in the Message displayed on the quote or Message displayed on statement field. That's why it show up when you print the quote.

I've attached a screenshot below: 

Another possible reason could be,  in the Custom Form Style you've entered your bank details in the Message to customer on or Add payment details and footer field, please see the other screenshot below:

Note: Let's make sure to remove the description you've entered into those fields. That should do it.
