I am about to take possession of an Oce 2280 and will probably go with an Onxy RIP based on some advice about color proofing. But I know there are different versions and licensing options so I would appreciate some advice. Do you have to buy the RIP with licensing for the particular printer you are using or do you have access to all printers it supports? IF I wanted to use it on two workstations, but not at the same time, do I need two licenses? Since the 2280 is older I may be able to find a used copy on ebay is my hope. Thoughts?
