Unable to install Epson TM-U220B[U220 with UB-U02III usb interface] on Windows 7 AND XP!

I have recently purchased receipt printers (Epson TM-U220B[usb connection]) to use in conjunction with a POS program. I am running Windows 7 64bit HP I am unable to even print a test page (from windows) to them at the moment - the printers WILL print a Self Test page direct. Here are the steps that I have taken: -Disconnected the printer. -Uninstalled all EPSON driver software & restarted the computer. -Reinstalled EPSON Advanced Printer Driver V4.52 (APD_452E) with these configuration settings: Setup Type Minimum Printer Configuration Add EPSON TM-U220 Receipt EPSON TM-U220 Receipt[US] Create a USB port -Restarted computer (for good measure!) -Connected printer. -Windows then installs device driver automatically with the following commentary: EPSON UB-U02III - Searching Windows Update > EPSON USB Controller For TM/BA/EU Printers - Ready to use At this point the printer is shown in Devices and Printers under Unspecified with the name UB-U02III (which it looks like is the model designation for the USB adapter board on the back of the printer). The installed printer (installed via APD driver) EPSON TM-U220 Receipt printer is showing up as Not available in its status. What am I doing wrong?? The driver is downloaded directly from Epson on their product page for the U220 (https://download.epson-biz.com/modul...&pcat=5&pid=42). Incidently I get an identical result trying the above on a Windows XP machine. I hope this is concise and not to waffly! Thanks Mike
