Thankfully I don't use SAP but...
Why SAP cannot output the image of the bar code but instead sends it encoded in the bar code font seems a bit silly to me, it can't be that hard. The unicode font package is around £500 per machine and the install and licensing is a flipping nightmare.
I have installed over 50 of these font packages in the last 12 months just because SAP will not rasterise a bar code. What a waste of money.
