The year is 2089. The world has suffered greatly from EMPs from asteroids. The internet is no longer reliable(Bye bye SE). We now rely on printers to send messages. Our research has advanced, and now printers are aware-both of themselves-and to our needs. However, somewhere down the line they become self aware, and threaten to destroy human kind. What would be the best offensive attack on self aware printers to stop them from replicating and creating more advanced machines to destroy us?
There are 10 BILLION printers, about 20% 3D(to replicate robots to destroy), you have and near infinite amount of materials(except printer made ones), the printers are HIGHLY advanced, pulling the plug or something like smashing them would not work. They are waterproof, made of titanium, have backup batteries that last at least 10 years, and any method that takes over 42 seconds will fail, as they will upload themselfs to the I.S.S(controlled by printers) and will ultimately devise a plan to nuke the earth.(Note on the I.S.S, It is abandoned, therefore printer territory, but not populated as only their emergency protocols will upload them there.) The printers can manufacture almost anything on the earth.
