http://www.cs.uni.edu/~mccormic/4740/documentation/parallel.pdf An Wang, Robert Howard and Prentice Robinson began development of a low-cost printer at Centronics, a subsidiary of Wang Laboratories that produced specialty computer terminals. The printer used the dot matrix printing principle, with a print head consisting of a vertical row of seven metal pins connected to solenoids. When power was applied to the solenoids, the pin was pushed forward to strike the paper and leave a dot. To make a complete character glyph, the print head …

WebTo transmit a byte, the serial device driver program (running on the CPU) sends a byte to the serial port”s I/O address. This byte gets into a 1-byte “transmit shift register” in the serial port. From this shift register bits are taken from the byte one-by-one and sent out bit-by-bit on the serial line. Which is fastest port for data transfer?
