Today I was talking to a ricoh engineer while we were troubleshooting some issues on the ricoh mfp's I manage and he talked about coexisting printerdrivers from version 4.0. I emediatly downloaded and installed V4.2 and YES eureka I got 2 Ricoh drivers on my printserver instead of one.If you choose to install the UPD without version number it will overwrite the existing driver.

1: This wil overwrite your existing driver

2: This driver wil be installed as coexisting driver next to the older driver

 

 As you can see the drivers are installed on one printserver and coexist next to each other.

 

I think you can now easier test new drivers cause you can fallback to older drivers without having to reinstall them.
