In almost each enterprise there is a software support for business processes. With a growing number of the applications there is an increasing demand to integrate those applications in order to have an effectively working environment, which generates profit. In enterprise applications integration there are few principles, each with their own advantages and disadvantages. However, the message-oriented middleware layer proves to be the best solution to many integration scenarios. This work deals with an enterprise of applications running on multifunction embedded office devices based on Java ME platform, and introduces an in-house developed communication middleware layer to integrate those applications. The resulting software component applies principles of messaging in a printing management SOA environment to communicate with a print server using a designed set of messages.
