What type of support do you have for bi-directional communications?
Does it handle the different protocols from each of the different
vendors since they all provide information in different ways.
The diagram I put together isn't cast in concrete but it did provide
a way for each vendor to provide specific protocol support through
a defined print system interface from a module that knows the specifics
of their individulal protocols. If the layering isn't what is needed
and we can actually make one generic interface for all that is fine by me.
