To convert an Epson U220 model printer you will need an Epson compatible Connect-IT interface card.

Enabling communication between the card and the printer

Turn the printer over and remove the screw holding the protection plate over the dip switchs

Locate the 2nd bank of dip switches

Set switch 2-4 to ON

You can then self-test the printer to see if the Serial interface has been changed. If the interface still says "Serial", set 2-4 to OFF and set 2-8 to ON. You can then power off printer and perform another self-test. With 2-8 ON, it should now show as "Parallel or other" as its interface. This may vary from older U220s to newer ones, so results may vary.
