this is what I dont understand. so many apps are almost website-like in functionality, and you can save a shortcut to the desktop / main screen and it will launch / look like an app. complete with notifications (if enabled). What's the barrier? (another poster mentioned not knnowing anything outside of the appstore, but then "Share -> Add to Home screen" is a pretty damn simple flow.

looks like this is a variant of the other "portable mini thermal printers" available on aliexpresss https://www.aliexpress.com/item/1005002247175933.html

possible these are compatible or at least similar enough, many similar products re-use modules and microcontrollers.

kudos for doing the quick research into the actual topic and background of the situation at hand instead of soap-boxing about hypotheticals.

This should have been mentioned in the original post as it gives some much-needed perspective about the scale of the contribution.

we use these in our CI/CD pipelines as we deal with embedded hardware. they work absolutely awesome for power cycling stuck USB peripherals or powering USB-powered boards for tests.
