I would use it with the adhesive thermal paper for labelling up infrastructure, it sounds like it could make a decent administration machine. An Ethernet jack might be needed though.
This has potential advantage of being able to register the thing you label in a database.
It makes me think about when I was young, and my friend had the Sinclair ZX80 and the printer that came with it.
I think there's lots of creative use cases for it, I could imagine printing out chunks of my source code as I'm programming, to reference as I work on other parts.
I’ve imagined using a thermal printer as a semi-unattended packet radio terminal that wouldn’t lose messages when the batteries died.
