is this code actually compiled?  i swear @typedef doesn't work with trailing
commas

Oh I didn't know that. Modified as you suggested. However, it did compile
before... And I just searched in the code base, it seems there are other places
that use @typedef with trailing commas, like:
https://cs.chromium.org/chromium/src/chrome/browser/resources/settings/settin....


printerQueue will be used when manually setting up a CUPS printer, see mock
here:
https://docs.google.com/presentation/d/1FTAbefCL14zkYedIHGAyWhatuIIstUlLTYSCU....
I will work on it very soon.
