I bought Ricoh SP 210su MFP. It refuses to work on a Linux OS(Fedora 21) based computer. Though It gets detected when the USB cord is attached but refuses to work for want of proper driver. I tried all that's listed there in openprinting.org, linuxfoundation.org. etc. to no result. Any help would be much appreciated. P.S. I was told that Ricoh supports 'openprinting' which prompted me to the decision of buying the same!
