I have a Ricoh SP 210su printer and I am using Mountain Lion. When I connected the printer, Mac detected it and I configured it with Generic PCL 6 driver. However, when I fire a printout, it streams the document and after sometime says "finished printing...", but nothing gets printed. Do I need a different driver? I tried installing the driver for Ricoh printers that Apple provides (http://support.apple.com/kb/dl902) and tried configuring the printer, but could not find my model from the list of models supported. Is there any other way of making the printer work with Mac?
