Contact The XeroxConnection or your Xerox representative for connectivity andapplication software information for this configuration.Macintosh workstationsMacintosh PCs are generally connected to an AppleTalk network.They may also be configured to connect to Ethernet. The typeof LAN you use in your facility depends on the number ofMacintosh PCs you want to connect to the LPS. If you want onlya few of your Macintosh PCs to be capable of sendingdocuments to the LPS, then an Ethernet connection may bemore cost effective. If you have a large number of MacintoshPCs in your facility and you require all of them to be capable oftransmitting to the printer, it is less expensive to use AppleTalkand convert to Ethernet through a communication module.AppleTalk network interfaceThe standard Macintosh LAN configuration is through AppleTalk,as shown in figure 4-9. Most networked Macintosh PCs useAppleTalk to communicate with a printer.Communication protocols The LPS does not accept input directly from an AppleTalknetwork. AppleTalk must first be converted to Ethernet, so acommunication module such as Shiva’s FASTPATH is necessary.FASTPATH converts AppleTalk communication protocols intoTCP/IP protocol on Ethernet. The TCP/IP print jobs can then beconverted into XNS print jobs by a front end processor.4-8 XEROX 4050/4090/4450/4650 LPS PRODUCT REFERENCE
