Hi there--I have a new MacBook Pro OS 10.9.5 & I'm trying to get my Ricoh Aficio SPC 820DN to function on it. I successfully installed the driver, but I'm not sure what the next step is to get it to talk to my computer. When I went into my system preferences file & clicked on the printer icon, it was not seeing the Ricoh printer. Where do I go from here? Thanks for your help.--Jeanne
