Your GUI thread would have to polls some common variable, but polling is not possible in a GUI (unless you have a manual "refresh" button). The other (and most common) solution is to have the printer thread notify the GUI thread. But this requires the printer thread to be able to send some event to the GUI even loop. Most GUI libraries support this, except tkinter...
Unless noted otherwise, code in my posts should be understood as "coding suggestions", and its use may require more neurones than the two necessary for Ctrl-C/Ctrl-V.
