3.2.2 Service Provider “Packaging”

WOSA/XFS service providers can be “packaged” into DLLs in a variety of ways:

• One service provider per DLL; for example, a vendor might produce a journal printer DLL, a receipt printer DLL, a cash dispenser DLL, etc.

• Multiple service providers per DLL; for example a vendor might produce a DLL which contains the service providers for all XFS-compliant printers.

• All service providers for a specific vendor in a single DLL.
