Need help with power supply for printer

Hi there I have recently purchased one of the Epson AX3s however I am lacking a power supply, after google searching this for a number of days I came accross this and was wondering if you would be able to tell me the details of the power supplies.

 

When I tried checking for power supplies at the Epson site, it asked for an SKU number for the printer. It didn't have any information on "AX3" at all.

 

Yes this is for a laptop, sorry if this is posted in the wrong forum im new to this and thought it was in the other hardware catagory.

 

I found out that the Epson AX3s is a vintage laptop like the Tandy TRS 80. According to a post I read on another forum, it's got a "weird" 3-prong connector. You may not be able to find a power supply for it at this point in time.

 

If i cant find a power supply for it then I think I might just have to find out what the pins on the connector are for and build a power supply for it then. I have started searching for the power connector pinouts but have had no luck so far.
