I am trying to attach an epson printer TM-T88III to one of my terminals. I am using the epson ADK ospos software to set up the printer. When doing the health check I keep getting the result OPOS_E_ILLEGAL.
I can not for the life of me figure out why I am getting this result. I have tested the printer and it is working perfectly (I took if off of a different machine that was working perfectly)
Any ideas what is causing this?
Thanks!
