That remote scan feature will net the bad guys lots of hits right around tax time when everyone is making copies of their tax forms. I have an HP wireless printer, but I only turn it on briefly when I need to print something. The rest of the time it is off. But now that I know it can be a problem, I plan on adding a password and if I can figure it out, I will change the firewall settings on my wireless router to stop any external queries to the printer.
