I am surprised Sharp is not beating their drum more about this as I think it is an industry first.
I have been involved in several mobile print installs lately and they sometimes involve allowing non employees to use a companies wireless LAN. Usually you also need a PC turned on all of the time with a wireless app like Breezy installed and running on a local PC. This could be potentially problematic from a security point of view. Sharp's new approach by making the MFP the wireless access point for mobile printing would greatly reduce this threat in the eyes of the average buyer.
Sharp's approach might also make it simpler for the average user to connect and print. The user would likely have to install a Sharp app on their mobile device to make this happen but in my example they need to load a Breezy app.
You can purchase a Wireless router from Staples for $30.00 so how hard can it be to put that inside a copier as a standard feature?
