UNO: Possible to get printing progress?

[Ignaz Forster]

Hello,

is it possible to get the printing progress of a document via UNO? This 
would make it possible to give the user some feedback when printing 
large documents.

The closest thing I've found is the PrintJobEvent 
(http://api.libreoffice.org/docs/idl/ref/structcom_1_1sun_1_1star_1_1view_1_1PrintJobEvent.html), 
however the PrintableState seems to contain only very basic information 
(Started, Completed, Spooled)...

Thanks a lot,
Ignaz
