Types of printer interfaces

by:Tuowei     2019-09-09
The printer is connected to a computer using a variety of different interfaces, such as parallel, serial, SCSI, USB, or IEEE 1394.
The network-enabled printer also has a built-in
In the network interface, connect directly to the ports on the network so that they can be shared on many computers. .
ParallelA parallel printer interface is called (IEEE 1284).
This port is sent by 8-
Bit information flow to the printer.
It uses a standard parallel printer cable with DB-
25 connectors connected to the computer and 36-
Pin-centralized connector for connecting the printer.
The maximum length of the parallel cable is usually limited to 10 feet.
The reason is that the data integrity is reduced, and the printer may lose data at a larger length.
The Serial Printer Interface sends one bit of data to the printer at a time.
This interface needs to be configured with serial communication parameters including baud rate, parity bit, or start and stop bits.
Serial printers are rarely used now, but sometimes point matrix printers use this interface.
Universal Serial Bus (USB)
USB ports are the most common port types on most PCs today.
That\'s why it provides a good Printer Interface on small and medium sized printers, desktop printers, and scanner combinations. (
And many other peripherals).
USB is much faster than most other types of printer interfaces.
The USB printer has plug-and-play compatibility and can be automatically detected and configured by the operating system.
IEEE 1394 is also known as Firewire because it has super fast speed when it first comes out.
Although there is no built-in firewire interface on many printers or PCs.
It is suitable for high-end printers and is very popular on laptops.
Today, most high-end printers, even some of the more basic ones, come with built-in
In the network adapter, or an adapter can also be installed.
The network printer is directly connected to an idle network port on the hub or router and is assigned a network identity, such as an IP address.
The printer uses a standard network cable with RJ-45 connector.
Sometimes in larger companies, they use a pc directly connected to the printer as the printer queue manager.
WirelessToday is one of the more popular interfaces in Printer connections, which supports 802 wireless connections.
Bluetooth or infrared standard.
The main advantage of the wireless connection is that both the computer and the printer can be moved and there is obviously no wires.
The disadvantage is that there is a limit on the scope of network coverage.
They are also prone to interfaces from other power sources, and the reason why most wireless printers are slow is that the data is usually heavily checked for errors.
Interface of Small Computer System (SCSI)
There are very few printers with SCSI interfaces.
As faster printer interfaces have been discussed, these types of printers are becoming obsolete.
