Loading images without promis

[julian-weinert]

I'd like to load an image without using promises. Unfortunately escpos uses promises heavily and thus forces me to wrap my entire print handling into yet another scope.
I generally dislike promises because they force you into an endlessly growing scope tree.

Is there any way to do this differently? await cannot be used, as doing so results in a SyntaxError: await is only valid in async functions and the top level bodies of modules

Thanks for any input
