Unfortunately, we can't help you with your cutter/engraver machine. You'll have to either find the documentation for your machine, or find a forum or some other online documentation, to learn how to use it.

I guess what you need to do is change the red and blue objects to vector paths for cutting or engraving, right? You should be able to import the JPG, and use Path menu > Trace Bitmap. Use the multiple trace option "Colors" and set for 4 Scans. Also check Smooth, Remove Background.

When the trace is finished, it will be right on top of the original JPG, and it might look like nothing has happened. But in fact, you have what you need.

Object menu > Ungroup. That breaks everything apart into separate pieces.

As far as I understand, you want to use some feature of your machine which will trace raster images, for the black parts. Since Trace Bitmap has traced everything, you'll need to delete all the black parts. After that, it would seem that your image is ready to send to the cutter. Of course I have no idea how to do that.

If your machine needs some special format, such as DXF or gcode or something, Inkscape can do that. Whether it's in the Save As menu or comes from an extension, depends on specifically what you need. Since you didn't say, I can't offer any suggestion.

But now you have the red and blue vector paths, and the black parts are still connected to the original JPG, so they are raster. Is that what you need?

Personally, since Inkscape can so easily create text, I probably would draw that image from scratch in Inkscape, rather than search around for raster images made by someone else. The text would come out much more precise. Although perhaps by the time you cut everything out and engrave it, you lose all that precision anyway. But I just thought I'd mention that it doesn't make sense to trace text, when Inkscape can create text. Personally, I would still need to import the santas, because I can't draw very well. But anyway, just a thought.
