What is a USB printer port?
USB printer port is a socket built into the printer as a way of connecting the printer to the computer. The USB plug is connected to the port and then to the USB port on the computer, connecting the device. via a USB cable. This removes the need for a bulky printer cable connected to a parallel port. This also means that there is no problem to combine the printer to a computer that comes without a parallel port like most laptops. Because the USB uses a standard socket on the computer and one of the three standard plugs on the device itself, the modern device for the modern computer is certainly connected. It is technically possible for more than 100 USB devices to be connected to the same PC.
traditionally printers used a parallel port connection. It is a multi -sector and a socket system that takes its name from the fact that data transmitted via each pin is sent at the same time the difference from earlier serial ports, where only one pin was active at once. The main disadvantages are that the plugKa is quite clumsy and most computers have only one parallel port, while some new desktops and most laptops do not have a parallel port.
Most new printers instead work via the USB printer port. This name is simply used to identify a specific USB port used rather than a special design. The cable is usually a standard USB plug known as type A, at the end of the computer, with a square USB plug, known as type B, at the end of the printer. While USB cables can power some devices directly from the PC, this is usually not the case with the USB printer.
In the settings with an older printer that does not have a USB socket, and a computer that does not have a parallel port can be used an adapter. This is usually in the form of a cable that has a USB plug on the end and a 15-round socket on the second. It is important to realize that it is a female outlet rather than a male plugu. This means that the standard parallel cable is still needed that runs from the printer to the adapter. Although this setting works for most printers, it is usually not suitable for some other devices that can be connected to a parallel port like a scanner.
In most cases, the computer operating system will be automatically recognized by a printer connected using USB ports. If this is not the case, the driver will have to be installed: it is a small piece of software that coordinates the operating system and hardware device. If the operating system does not automatically find automatically, it can usually be installed from a CD that comes with a printer or downloaded from the manufacturer's website.
