HotSpot Printer and Routerboard 1200. Problem

Good morning,

We have a problem trying to connect a printer brand Technologic (HotSpot Printer) with a routerboard 1200.

We have connected over IP to mikrotik Brinding by MAC, and if tested pinging ping does well. The problem is when I tried setting fares or MT, then the message that we get is:

OK … Conection
Connecting to Mt … ERR

We have created user in userma admistrador and we have put that user to the printer, we have created a regular user and I have set, but we no longer make that mistake.

We found this manual: http://www.technologic.pl/download/HotSpot_Printer/Mikrotik_5.XX/beta1.5/Quick_guide_beta_5.pdf but when we got to the point 5 we get stuck.

thanks
