[Qt-interest] Update print progress

[Stephen Chu]

Hi

Is there any way to update the progress bar in the system print progress 
window? By progress window I mean the window that pops up during 
printing. On OS X it's showing a progress bar that is in undetermined 
state. Not very helpful.

I want to update the progress when printing a large image. I can use 
QProgressDialog but that will sit over the system one and not very 
desirable.

Thanks.
