A null modem adapter. Null modem is a communication method to directly connect two DTEs (computer, terminal, printer, etc.) using an RS-232 serial cable.The name stems from the historical use of RS-232 cables to connect two teleprinter devices or two modems in order to communicate with one another; null modem communication refers to using a crossed-over RS-232 cable to connect the teleprinters ...
A Direct Cable Connection dialog box on Windows 95. Direct Cable Connection (DCC) is a feature of Microsoft Windows that allows a computer to transfer and share files (or connected printers) with another computer, via a connection using either the serial port, parallel port or the infrared port of each computer.
The host sent ASCII characters to the printer using seven of eight data pins, pulling them high to +5V to represent a 1. When the data was ready, the host pulled the STROBE pin low, to 0 V. The printer responded by pulling the BUSY line high, printing the character, and then returning BUSY to low again. The host could then send another character.
Printer cable refers to the cable that carries data between a computer and a printer. There are many different types of cables, for example: Serial: RS-232, EIA-422; Parallel; FireWire; USB; Parallel port printers have been slowly phased out, and are now difficult to find for the most part, being considered as an obsolete legacy port on most ...
Note that the printer itself is not necessary to be wireless. AirPrint is a feature in Apple Inc.'s macOS and iOS operating systems for printing via a wireless LAN (Wi-Fi), [5] [6] either directly to AirPrint-compatible printers, or to non-compatible shared printers by way of a computer running Microsoft Windows, Linux, [7] or macOS.
Printers can be connected to computers in many ways: directly by a dedicated data cable such as the USB, through a short-range radio like Bluetooth, a local area network using cables (such as the Ethernet) or radio (such as WiFi), or on a standalone basis without a computer, using a memory card or other portable data storage device.
Through the use of the Printer Preferences program printers could be connected to the serial port as well. Amiga also had support for a virtual device "PRT:" to refer to printer.device so, for example the command "COPY file TO PRT:" caused the file to be printed directly bypassing parallel.device and the default printer driver.
An IEEE 1284 36-pin female on a circuit board. In the 1970s, Centronics developed the now-familiar printer parallel port that soon became a de facto standard.Centronics had introduced the first successful low-cost seven-wire print head [citation needed], which used a series of solenoids to pull the individual metal pins to strike a ribbon and the paper.
