Somemone called? :-)
There is a WinXP security update, that interferes with Epson's colour management. This update is included in SP2, but it can also be installed under SP1. Unfortunately, I can't remember which one it is (I'm not at work right now).
All Epson-drivers that are version 5.5 or higher contains a fix for this issue. Look at epson.co.uk for the latest driver for the R200.
You can also work around this issue, by using a program that uses ICC-profiles (Photoshop for example), selecting the Epson profile, and then disable the colour management in the driver (Printing properties -> advanced).
This applies to all Epson printers, not just the R200.
