Summaries:
Printers were the main topic of this video clip. There were three separate printers that were mentioned throughout the video: the Dot Matrix Printer, the Inkjet Printer, and the Laser Printer. After learning how to identify the printers, the video progressed into how to identify the four different connectors: centronics, parallel, USB, and SCSI. The main purpose of this video was to demonstrate how to properly connect a printer in order to enhance its performance.

Definitions:
1. Dot Matrix – a grid of dots that are filled selectively to produce an image on a screen or paper. 2. Inkjet Printer - a printer in which the characters are formed by minute jets of ink. 3. Laser Printer – a printer, linked to a computer, producing good-quality printed material by using a laser to form a pattern of electrostatically charged dots on a light-sensitive drum, which attract toner (or dry ink powder). The toner is transferred to a piece of paper and fixed by a heating process. 4. Spooling – Software that manages sending jobs to the printer. When an application prints a document, the formatted output is stored on disk, and the print spooler feeds the print images to the printer in the background at slower printing speeds. 5. Queue – a list of print job waiting to be printed 6. CYMB – Cyan, Yellow, Magenta, and Black
After watching this video clip, I’ve learned that the Dot Matrix printer is well outdated. The reasonable option would be to choose between an Inkjet or a Laser Printer. I personally use an Inkjet printer in my home office. A useful tip that I’ve gained from this
