Hi, We have bought a number of MS Surface RT for the school to work with Office 365. everything worked great until today! I want to connect the MS Surface RT Tablet to our Ricoh Photocopier Machine 4500 series which is supported by RT. The special app has been downloaded (Ricoh Class Driver) and i have managed to connect the tablet to the printer without any problem. However, for extra security I have locked the photocopier and only users with a user code can print. The test page is sent to the photocopier but it does not print anything due to restriction rights. Usually in the printer properties there is a tab that allows you to enter the user code but this option is not available in Ricoh Class Driver. Any ideas on how we can solve this problem without unlocking the photocopier machine? thanks!
