That site says it’ll give you an AppImage or a Snap—I didn’t mention the AppImage format in my last post but it’s effectively like a DMG on macOS, so you just distribute the file and users only have to mark it as executable and run it. A VM is plenty for testing that your app starts and lets you design labels fine, but you’ll be in for a world of trouble if you try interface physical hardware (like the thermal printer) from one. You could always just make a live USB of a popular distro like Ubuntu or Fedora and download and test your app on real hardware—booting Linux on a recent Mac would be a challenge so you’d want to use an older one or PC hardware for running a live USB. Electron seems to support ARM, the processor architecture used by the RPi, so I would think you’d be good to go there aside from your app maybe being a little slow. You will want to talk to someone else too since I’m sure I’m forgetting something, particularly about the Raspberry Pi.
