Explanation:
Here’s a fun trick: print a multipage document to your USB or Wireless printer. After it starts printing, gently pull out the USB cord or disconnect your computer from the wireless network. In most cases, the document will keep printing, indicating your printer is printing it from its memory instead of from the computer directly. This is a feature common to almost all modern printers. Printer manufactures didn’t design this feature because they wanted to serve people who trip over their cords or have bad wifi; they added memory to printers for three reasons:
1.To make printers print a little faster. Memory lets a printer accept the document from the computer as fast as its connection allows, so even if the computer slows down later (maybe because you decided to play a game), the printing won’t slow down.
2.Most modern color printers work by combining together different colors of ink in a marvelously complicated process. To make this work as well as possible, each printer has a sophisticated printing language which describes how the document should look. Modern printing languages are almost all almost programming languages so the computer can exert full control over how the printer works, but to run a computer program, the printer needs to load the entire program into its memory before it can start running (and printing) any of it.
3.In addition, many modern printers support more than one printing language. For example, high-quality printers designed for business tend to support not just their own native language (usually called PCL, or Printer Command Language) but also Adobe Postscript (PS), which actually is a programming language widely used for even non-printing tasks, such as being the language Mac OSX uses to display 2-D windows
