<P> The older parallel printer ports had an 8 - bit data bus and four pins for control output (Strobe, Linefeed, Initialize, and Select In), and five more for control input (ACK, Busy, Select, Error, and Paper Out). Its data transfer speed is at 150 kbit / s . </P> <P> The newer EPPs (Enhanced Parallel Ports) have an 8 - bit data bus, and the same control pins as the normal parallel printer port .
