the method of interfacing this printer to a data source depends on the communication options installed in the printer. the standard interfaces are an rs-232/rs-422/rs-485 serial data port and a bi-directional parallel port. the optional zebranet?printserver ii enables printers to be connected to 10base-t ethernet networks. in addition, the ibm?twinax or ibm coax option is available for those applications that require them.
