Another Printing Question

I have a customer that using Loftware for label printing. The software uses and RFC listener to receive print requests initiated by SAP.

The documentation states

"Similar to receiving IDocs, the [RFC] Listener will register with SAP. This will take the form of a CALL FUNCTION ... DESTINATION statement in and ABAP program in SAP"

Since xMII doesn't provide ABAP code. do you think its possible to connect to thier RFC listener using Business Logic?
