The problem is either the printer and or the printer cable or the printer baud rate in your TV-220.
I simplified the problem and baught a special printer cable from Black Box that had dip switches on it for in oder for it to work on different printers.
If your using an EPSON printer you close to being able to print.
You just need to get the TV-220 to slow down the print baud rate to not overload the printer.
Let me know if I can help?
