to clarify, last time I tried to update the host application it told me to update the fw too. Ive got my printer sitting fully operational but my pc had a hd failure which lost my v81 host app I had all configured. My hope is to get the same host app that came with the v81 update I did a while back and just continue on my way. It takes a bit of effort to get my additional code modifications into the new update and I am not sure if I can just use the latest version host app with my .81 firmware that is setup in my controller already. It does connect but I have not gotten further than that in my testing. I have not had time to monitor the test print.
Hopefully that explains what Im trying to do so you can better assist .
