While I was browsing their website, I encountered a page where I have found some barcode samples.
You can check the page as well to see exactly what's this all about, but I didn't see anything related to your inquiry: http://www.free-barcode.com/pro/
However, after further searching, I have downloaded the application and installed it, and as you can see, Yes, it supports interleaved 2 of 5 barcode format.
