Hi, yes we do this since years.
We use the Rx, Tx (Pin 5,6,7) at DP610 and DP610TM.
We drive 3 RS232 slaves by swithing with my switch-box.
printer, logger, in/out-device

I also wrote a printer-driver to print in 12 languages all characters you want, graphically.

btw: Tx-ready is not valid, is allways True.
DP610TM: There have to be an RX input level Otherwise you can't send TX-messages.

Epson TM-U295
It is a cash printer.
You can also put DIN A4 format or other format.
I have build a communication from Display to printer an from printer to display.
You can connect each printer with RS232 port.
Read the documentation of the printer. There are the special commands.
Epson is very good for this.

Using Pins 5,6,7  as suggested and some example code we managed to get it working
Thanks again to all for your time and input
