Do you mean a LLM to write printer drivers? For that I think any of the coding LLMs should be able to help
Or do you mean using an LLM to do the raster -> FGL format translation? While I’m sure it might be possible, feels like an awful waste of resources, and when it comes to printers, you kinda want the guarantee that what comes out is the same that comes in.
This lets you do pretty much the same thing in the post above, but have the colors tied to Grafana metrics. It's been great to make very intuitive dashboards, especially building dependency graphs and annotating them with live data.
