Kitchen printer to print only food items

Just i want to print only food items on kitchen printer and disable bar items. How can i do it?

In print jobs configure mapping to product group or product name.
Default will be all (straight *s)

Can you give me more details? Or a picture? What should i put for bar items and for food items?

Depends on your setup, how you set group codes on products etc.
Print job mapping could look like this but there are many ways to map and configure products etc.
By groupcode is probably most common/basic.

Also there will be more options in image as thats in v5 and guessing your using v4?
