The correct answer is a. unplug printer from the outlet
To connect a printer to your computer, never unplug any device from the power supply. When a device is turned off, even if it is connected with other devices via cables, it will not be recognized by other devices because there is no power.
To connect your printer to your computer, perform the following:
1. Plugged in both devices and turned the power on.
2. Connect the printer to the computer via printer chord or USB. This is for printers with cables or stand-alone printers only.
3. Sometimes, printer can easily be recognized by the Operating System or OS. Upon connecting each device, the OS can now automatically install the printer software to the computer. In some cases, auto installation cannot proceed. If this is the case, you must install the printer driver before you can use the printer. A driver is a special software that would allow the printer and computer communication smoothly.
4. After driver installation, you must perform a print test to see if the connection is successful.
