client printer drivers for cups

I have set up a cups print server using SuSE 8.1 which seems to work really well from our Win 2K clients, but from our Windows 95/98 clients I can`to print colour! The problem is that I am using the Adobe postscript drivers, the win 98/95 version does not seem to generate the right sort of postscript with colour photos etc. Which printer drivers are other people using on older machines? I don`t want to use raw print queues as I want to use print quotas. Rob Keeling Network Manager Queen Elizabeth`s Grammar School
