I realize that `numberOfFormatsInReceiveBuffer` will give the number of labels left to print, but for a printer that's shared between multiple people, that number will also be shared between people. I don't know of a reliable way to know when a specific job is finished (unless it reaches 0).

Is there any kind of print job status tracking or ID associated with a print command that can be used to display progress?

I'm using Android, if that makes any difference.
