What is the difference between a serial and parallel interface receipt printer? -

The parallel interface using a 25 pin connector, and is more of a printer standard. (some new computers have abandon this in favor of USB). The serial printer uses the 9 pin connector in many cases. This can be programmed to use COM1 or COM2. Be sure to read the instructions carefully, and learn which ones your computer has. Very old computers also used a 25 pin connector for a serial port, but it was a MALE connector instead of a female connector. You would not mistake the two. Good luck and Happy Computing!

The main difference you will care about is how it connects to your computer. Printers generally either use a parallel port, a serial port, or a USB port. Most newer computers have parallel and USB and are phasing out the serial ports.

The parallel interface should provide faster printing. There is also a USB interface which is faster.

A serial interface can only transmit one bit at a time. A parallel interface can transmit more than one bit at a time hence parallel. Parallel interfaces are therefore faster, but much slower than a USB 2.0 interface. A printer with USB is preferable.

One s serial, one s parallel!!!!!!!!!

Hi A receipt printer may sound like a straightforward piece of equipment, but be warned. There are many different manufacturers and models offering a wide range of features. Understanding the difference between these features can greatly increase the speed of checkout and the productivity of your registers. A serial interface is the type of attachment that can run from a printer to a PC. Serial ports on a computer are male and have either 9 or 25 pins. What is a parallel interface? A parallel interface is the type of attachment from the parallel port of the printer to the parallel port of the PC. A parallel port on a PC always is a 25 pin female port.
