Epson tm-u220 using a usb-to serial adapter on Windows 7 64-bit

I am trying to install an Epson TM-U220 using a usb-to serial adapter on Windows 7 64-bit.  I have tried several different driver combinations to include: the "manual" installation using .INF and .DLL driver files, a generic text only printer driver, and the Advanced Printer Driver (APD_450EWM).  On some machines, the text only driver does the trick and that is fine, but on others the print comes out garbled.  I feel that in these cases, I could be using the Epson-provided APD.  The thing that I believe is causing my problem while using the APD is the use of the Trendnet TU-S9 Serial adapter coupled with the Epson Port Driver (they each have configurable COM port settings.)  

How should I configure these devices to get this all to work?

Thanks in advance,

    >>  using a usb-to serial adapter  <<   i have found many do not work correct - best use a PCI to serial adapter card

    Accepted Solution

    I was able to get this to function properly using the Epson-provided Advanced Printer Driver (APD_450EWM) by setting both sets of COM settings to Flow Control: Hardware, Baud Rate: 9600, Data bits: 8, Parity: None, Stop bits: 1 and making sure no other printers were configured on that same COM port.

    Thanks for you suggestion, but it can work with these settings
