I read the article. It sounds like the auto makers concern is that they don’t think they have been given enough time to solve the problem (the problem being one which may kill people while we wait for a solution).
I think we should give them all the time they want, as long as they stop selling cars without safe door handles RIGHT NOW.

Many label printers (especially the older ones) use a proprietary text-based language, and accept plain vanilla text input via their serial port. They don’t use a printer driver as such. To use one of them you have to learn their command language (usually pretty simple) and write a text file describing what you want to print using that language, and upload the file to the printer.
Start with the printer documentation and go from there.
Newer printers need linux drivers. Support varies.
