well if some one is sleeping you can awake him but it is very hard to wake someone up when he is pretending to be sleep.The poster was specifically referring to Plotters. Do you know of any Plotters that support wireless printing?
as you mentioned they are big limitation on plotters with wireless connectivity, and it is not norm of industry. i agree that this device can be used for lots of things, but lets agree on it it is not perfect device for a pro and industry.
