What is the difference between a serial port and a parallel port?
Parallel ports are easy to program and faster compared to the serial ports. But main disadvantage is it needs more number of transmission lines. Because of this reason parallel ports are not used in long distance communications. Let us know the basic difference between working of parallel port and serial port. In serial ports, there will be two data lines: One transmission and one receive line. To send a data in serial port, it has to be sent one bit after another with some extra bits like start bit, stop bit and parity bit to detect errors. But in parallel port, all the 8 bits of a byte will be sent to the port at a time and a indication will be sent in another line. There will be some data lines, some control and some handshaking lines in parallel port. If three bytes of data 01000101 10011100 10110011 is to be sent to the port, parallel port communication is faster then serial port.
How can you link RS232 serial data on COM1 to output on COM2?
Yes on a modern computer you will need a USB to 9 pin RS232 converter or previously use the LPT parallel port.
What connectors are used on a parallel port cable?
Many devices have traditionally been connected to a parallel port. The most common usage was for printers. Image scanners, external hard drives, and Ethernet adapters have also been created for the parallel port.
If you need to use a legacy termional application that communicates through a COM or a serial port what IrDA spec is likely to be involved?
None. The IrDA is only important if you are using an infrared transceiver on the serial port. This is seldom found in most computers.
What is difference between a parallel bus and a serial bus?
A Parallel bus has a relatively large number of wires bundled together that enable data to be transferred in parallel. This increases the throughput, or rate of data transfer, between the peripheral and the computer. A Serial bus can be defined as a transmission path over which the participants transmit their data serially, sequentially in time, and using a common medium. In the case of serial transmission, only a single communication link for transferring data from any given end to another one. In the case of parallel transmission, we use multiple numbers of parallel links for the simultaneous transmission of all the data bits in the network.
How do you redirect a serial port to output out of the parallel port?
You don't. If you are wanting to plug something into the serial port, and it is the same size as the parallel port (it isn't a parallel port, it's a different plug for the serial), use an adaptor. I'm in the same problem. I have a laptop and a program that uses com1 and need to redirect serial communication (com1) to a parallel port since the laptop doesn't have a serial port. i have an adapter for parallel to serial connections but need to remap com1. your can redirect lpt1 outputs with mode lpt1=com1 but not the other way round. If the laptop has usb just grab a USB to Serial Adaptor. Am in the same boot. A Point of Sales app need to be connected via a com port for Receipt Printing... The Printer is a ESC/POS Printer but has a Parallel Connection... Works fine under Windows, but not in the POS App. What is needed is some sort of Virtual COM Port to Capture the Outputs and Redirect it the a Physical LPT Port. In doesn't sound hard, yet no ones don't it...
When was the parallel port first used?
Parallel Port is one in which the entire data byte is transferred at once unlike bit by bit data transfer by a serial port. The parallel port first came into use in 1970s and were solely used for Printing purposes. However, currently they are rarely used.
How many USB port serial and parallel port are available in computer?
That depends on how many are installed. One used to be standard on the motherboard. Some modern PCs have deleted that port since USB is much easier to use. If your machine has PCI or other expansion card sockets you can buy parallel port expansion cards and add several. It is also possible to add parallel ports using USB to parallel port adapters.How many do you want?

Can you use a parallel port for a printer?
Yes. In fact, this is the most common usage for a parallel port.
Does a printer plug into a parallel port?
It depends on the type of printer! Some printers (older types, mainly) used serial, or parallel ports. Most modern printers use USB or wifi.
What are the components use in the parallel port?

What type of port cannot be used to connect to a printer?
If the printer is of an older type that has the appropriate logic circuits, connectors and compatiible printer driver software, a parallel port and/or a serial portcan be used if they are available on the pc.
When would you disable the serial port?
In the past, both the serial and parallel port were the most common means of data transfer and communication used by PCs. Serial ports were used for devices such as modems, mice, and serial port printers. However, in newer PCs, both the serial and parallel ports have been replaced by the use of USB ports. You should only disable serial port(s) if you are absolutely certain that auxiliary devices such as modems; printers; mice; etc.. are USB based and that your PC has enough USB ports to accommodate all of your auxiliary devices. Note: If at some point in the immediate future, you plan to sell your PC, it might be wise to leave the serial port as is.
How Can you access Parallel Port using c plus plus?
You cannot directly access the parallel port because the operating system is managing that device. Use the file system. The name of the parallel port is "lpt1:". Open that as an ordinary file for write, write to it, and you will be writing on the parallel port.
Which port is use for impact printer?
An impact printer (dot matrix) usually uses either a serial, or parallel port. It depends on the printer and computer ports available. Most modern inkjet or laser printers use either wifi or a USB connection.
Which network cable should you use to connect PC to printer?
Whether your printer uses a serial port, or parallel port, or USB port, or wifi, decides what type of cable you need. Name and model of printer? Have you looked on the maker's website or user guide for instructions?
