Epson printer tm-t88iv and tm-t88v swapping (01-11-18)

After using the printer for a long time. The carbon for the printer is already fading so I thought I had another spare t88 that was repaired and was just going to swap in the printer to see if it can work. It seems after swapping it cannot work. Maybe another driver is required but since it will not be swappable I decided to buy spare t88iv to replace it then send for the current to repairs.
