Unfortunately, creating a bar code is not as simple as just choosing a font.
First of all, you’ll have to choose what kind of bar code you want to create. There are all sorts of bar code variations.
Next, you’ll have to purchase a font for the type of bar code you have chosen. Bar code fonts are not included with macOS.
Finally, most bar codes require additional check codes to be generated with a formula or code. This capability is not included in Panorama, you’ll have to implement this yourself.
There definitely are Panorama users that have gotten bar codes to work with Panorama, hopefully one or more of them will respond to this thread. But the ability to create bar codes is not a built-in feature of Panorama or macOS.
