This might be worth a shot (from Ricoh's Knowledge Base) but I doubt that it will help.

Question
I am having several problems with the printer actually printing the page. I sent the page to the printer, the printer data in light flashes and printer says processing the page. The print queue says opening printer connection, printing, processing, closing printer connection, and then nothing comes out of the printer. It prints only about 25% of the time. The other 75% of the time I get 50% when I do not get the last page. This happens when I use most any application. I have reinstalled the printer driver twice with NO change.
Answer
When the data is transferred at 100Mbps, depending on network conditions, the controller is not able to receive all data packets and retry procedures occur. As a result, print jobs from a Macintosh takes a longer time to print out. To fix the problem you need to make sure that dual speed hub (10/100) is used between network and the printer and set the network speed to 10Mbps on printer. This setting can be changed under Menu, Host Interface, Network Setup and Ethernet. There is almost no effect on actual print time when the machine‘s network speed is changed from 100 to 10Mbps.
