Need help to print on dark cardstock using an Oki Pro 9542

Good morning all

Just joined the community and really need your help to print on dark cardstock to create wedding cards.  I am using a Mac and printing on a Oki Pro 9542 which has white ink.

As an example, I would like to produce something similar to the image below:

I do not know the processes on coreldraw graphics suite 2023 to achieve this.  I would appreciate if somebody could help with what I need to do in the printer driver to be able to print colour on dark cardstock.  (This Oki machine has the ability to print using white ink in one pass when the card is fed)

Many thanks
