Abstract: A method for acquiring data from a point-of-sale (POS) system is executed by an electronic label system. The electronic label system includes a host and a virtual printer unit operable to communicate with the host over a network. The POS system is operable to obtain sales information from a database thereof and to transmit the sales information to the virtual printer unit. In the method, the virtual printer unit is configured to convert the sales information into print data that can be recognized by the host, and to transmit the print data to the host through the network.
