How to Add a Printer in Windows 7
Microsoft introduced Windows 7 as its flagship operating system in 2009. In Windows 7, you can quickly install a printer using Plug and Play technology. Plug and Play technology allows you to connect a printer to your computer (via USB cable) and have the printer automatically configured. If Windows cannot install the printer, a wizard starts and searches your computer and the Internet for a suitable driver. If it still cannot find a driver, you will be asked to insert the software that accompanied the printer.
Turn on the power to your printer.
Plug the USB cable into your printer.
Plug the other end of the USB cable into your computer. The computer detects the printer and will automatically install the drivers or ask you to install the software included with the printer.
Reboot your computer and your printer is configured.
