Yes DG... if I was to do this I would use the Excel and CSV file route.

There is a "Paid and Awaiting to Post" report available in the File Exchange area.

Although I've never used it, I would expect to find shipping information in that report.

Once it was in Excel then you would need to massage it using Excel to get it ready to export to your label printing software.

I'm quite sure it could be done if you are a bit of an Excel guru.

Might need a bit of VBA code to achieve I suspect tho.

I'm unaware of any existing 3rd party software solution tho.

But now that I think about it I might take a look into it to see if its do-able.
