Hi Tony,
I had the same problem while ago. I couldn't get it working by just sticking code in the middle of receipt, didn't work at all ...
The way around it ... finish document half way trough and start it again, that will couse 2 pages printed, but the duplicate will appear between them.
In addition to that i reseted paper cut percent so its not cut half way trough but keep it as one strip.
Downside: Extra white space in between "pages" which I couldn't get rid at all ... no mater what I done
