Is it possible to print two words inside the same black circle using different fonts, like the country name and size in this label ?

I tried to print each word in independent circles but, the last printed circle overrides the first one, using a sentence with CRLF between the two words has the problem of changing font, any tip?

You mean like this:

Wow!! That's exactly that.
It's good to know that it's possible because, I use an SBX that prints labels based in structured settings written in external config files so, this means that something is missing while interpreting those settings that I must fix.
Thank you very much

The key here is that the color specified in the //SETTEXTALIGN should act as "paint" (rather than "ink"). (And unlike real-world paint, this kind of paint covers perfectly, even white on top of black.)

So it's just a matter of outputting the background first, and then writing on top of it.

Note that for positioning your text, you probably want to set the //TEXTCENTER rectangle height to zero and use //SETTEXTALIGN to bottom align the upper string ("US") and top align the bottom string ("9.5")

Thanks for the addttional tips, precious!
The issue was very intrinsic to the SBX logic to interpret the settings but, in resume, I have configured the label in a way that, the SBX was drawing two circles each with one of the two words inside of it but, the second was on top of the first circle so, hidding the first word.
After seeing your example, I changed it to, first draw one single circle and, in sequence, write each of the two words, simple as that!

Thank you very much
