How can something print on my printer at home that I never sent from a yahoo search? Im confused.? -

I turned on my printer this morning and it printed 3 pages of a yahoo search term that I never in a million years would enter. How can this happen? No one else has used my computer.

if u have a wi-fi printer and an open network some body s computer might have connected to you re wi-fi and printed it. lock down you re wi-fi with wpa2 !!!!
