B-1Appendix B Host Computer InterfaceThis appendix explains the signals used in the printer’s paral-lel, USB, and serial (option) interfaces. It also lists pin assign-ments, signal functions, timings, connector specifications, andvoltage levels. For details on the network interface, refer to theIB-21E/IB-22 User’s Manual contained on the CD-ROM that issupplied with the printer.This appendix explains the following topics:• Parallel Interface• USB Interface• Serial Interface (option)The printer features fast data transmission with the parallelinterface. The parallel interface mode can be activated fromthe operator panel.SeeChanging Parallel Interface Modes on page 3-19.Use a parallel printer cable that complies with the IEEE1284standard.Nibble (high) [default]High speed data communication is used in compliance withthe IEEE1284 standard. Ordinarily, you should leave thissetting unchanged.AutoThe printer automatically changes its communication modeto the one the host computer is currently using.NormalThe printer uses the standard communication method pre-scribed for Centronics interfaces.High-speedThis mode enables faster data transmission between the print-er and the host computer. (Select this mode if printing prob-lems occur when the printer is connected to a workstation.)The pins of the parallel interface connector carry the signalslisted in the table inParallel Connector Pin Assignment. As-terisks in the table indicate signals that are low active. Thetable also indicates whether each signal is incoming or outgo-ing with respect to the printer.Parallel Connector Pin Assignment1.
