How do you print stuff on your computer?

Basically, you need to have a printer connected to your computer or home network. How this is done depends on whether the printer uses a serial, parallel, USB, or wifi connection - and what operating system you use. You then send data to the printer for it to print out on paper. A document you wish to print is showing on the desktop, click on File, Print and the document will be printer. For more in-depth information, search the printer's maker, or Google. Youtube also gives informative videos on most problems user have.
