Help setting up Epson Tm-T88V receipt printer

[kompolaga1]

I really need help to setup this printer to the software of Retailman. I have the demo new version of RM and am planning to buy it for 2 computers, but I still can't figure out how to use the printer with the software.

I already tested the printer with another POS software and it did print the receipt as it should, but I really like the Retailman but setting the printer up in Retailman is too complicated (with codes, drivers etc etc) with the other software I just plugged the Epson USB printer and it installed and was ready to use on the other Pos software.

Please help me set up the printer with RM and explain to me with detals because I have little knowledge with computers and we are planning to open the store this week.

So please help me set up the printer.
