RetroPrinter Support

Has anyone experience of the Retro-Printer with the Psion series?

So far we have not been able to even capture anything from Psion on a v3 module - it might be that it needs the power removing from one of the pins (which we allowed for on the v4), but I am currently at a complete loss.

After a bit of experimentation, using a Psion Revo and a Psion 3mx, we managed to get the Retro-Printer working with this.

The trick is to use handshaking set to 2 and using a v4 Module - presumably the Psion expects power on one of the three optional pins added by the v4 Module.
