I have found a working solution. Go to this link and download the PCL 5c driver for your version of Win7
http://support.ricoh.com/bb/html/dr_ut_e/re/model/mpc25/mpc25en.htm#Microsoft Windows 7 (x64) I had already installed the Series II driver, which worked for B&W (thanks joanne83). So I just downloaded and extracted the driver and pointed the Series II control panel to the new folder. When asked for what version I used the MP C2000. And now I can print in COLOR!!!
There are a few options that don't apply, but I just ignored them.
The key to this solution was that I found out that the HP Color Laser Jet 5 uses PCL 5c command language from this site
http://printerspecial.blogspot.com/2008/08/pcl5-pcl6.html . That little "c" was the key. Then a simple search for PCL 5c drivers for Win7 yielded the Ricoh page. Now that I know what to look for, I'm sure there are some better drivers out there, but I think I'm done looking. If someone finds a better driver please post it...
