Esko 7.5 installed successfully. I want to use FlexProof. I have installed Epson Stylus Pro 4880 on LAN and was able to configure it with FlexProof E Setup (created a profile with Kalideoscope) using Epson Print Port. Kalideoscope can print perfectly using the Generic setting but PackEdge says "No printer installed"

Does it require a separate print server?
Do i need to connect and install the printer locally?
How to get screened proofs?
How to proof from a mac as client?

Even a little help/guidance will be great.
