Appendix B Host Computer InterfaceB-2[ ]: Signal names in the Auto mode and Nibble (high) mode (IEEE1284).In the Auto mode and Nibble (high) mode, these signals are bi-directional.Detailed descriptions of the signals follow.Strobe* [nStrobe] (Pin 1)A negative-going Strobe* pulse causes the printer to read andlatch the data on the Data 0 [1] to Data 7 [8] signal lines.Data 0 [1] to Data 7 [8] (Pins 2 to 9)These eight signals form the data byte sent from the hostcomputer to the printer. Data 7 [8] is the most significant bit.Acknowledge* [nAck] (Pin 10)This negative-going pulse acknowledges the previous charac-ter received by the printer.Busy [Busy] (Pin 11)This signal is high when the printer is busy and low when itis able to accept more data.Paper Empty [PError] (Pin 12)This signal goes high when the printer has received a printjob and run out of paper.Online [Select] (Pin 13)This signal is high when the printer is online and low whenthe printer is offline. It goes low when the GO key is pressedto set the printer offline.+5 V DC (Pin 18)This line is connected to the printer’s +5 V DC line (+5 V ±0.5V, maximum 400 mA [Serial and Parallel total], fused).Error* [nFault] (Pin 32)When the high-speed parallel line control is on (FRPO O2=2),this line returns error status.Power Ready (Pin 35)This signal is high when the printer is turned on.The Paper Empty, Online, and Error signals are not used un-less enabled by the FRPO command (O2 parameter).This printer supports the Hi-Speed USB 2.0. USB (UniversalSerial Bus) interface specifications and interface signals areas follows.Basic specificationComplies with the Hi-Speed USB 2.0.ConnectorsPrinter: B-type receptacle (female) with upstream portCable: B-type plug (male)CableUse a shielded cable that complies with USB 2.0 and not long-er than 5 meters (16 feet).Transfer ModeFull speed (max. 480 Mbps)Power ControlSelf-power deviceUSB Connector Pin AssignmentNOTE2.
