I was looking at this online and it seems to be a problem with Epsom. Try going to Control Panel->Programs->Uninstall and uninstall the Epsom software.
If that works.
Once you have got it uninstalled, the drivers start page is
here. It should auto detect your OS and allow you to download the correct drivers.
I note that pretty much all OS' are in the list including, incredibly, windows 3.x!!!
If the CD/programs won't allow you to uninstall, you may be able to do it from the device manager. Click on Start then Right click on Computer and select manage.
In the devices tab you should be able to see your printer. There you can right click and uninstall.
If none of that works and you need to get into safe mode, you can do this most easily by going to start, run or search and typing in msconfig
change to the boot tab and select Safe Boot. You'll need to do the same again to stop it safe booting. In safe mode you can use the same instructions I gave you above to uninstall the printer.
Other advice gets incredibly technical incredibly quickly....
