Does anyone know how to print from Yosemite to Ricoh Aficio MP C2550? I have downloaded all the drivers I can possibly download. It did not show up in the printers/scanners preferences so I added it by IP address. I press print and it says connecting then the printer is not responding. This is a new printer for me, in a shared office space, so I'm not sure how to fix this. Also, my Brother MFC-8710DW also stopped connecting to my imac today too! (2014 iMac). I'm so frustrated, any help would be greatly appreciated.
