Hello guys,
I tried it and got a reply.
So that worked.
After being sure that it is only Eth issue, I added a small switch in between, I remember that once I did a similar work-around at a LAN connection at my friend's house during a LAN party (yes, I am that old).
AND I got a reply from printer! DWC smiled at me.
I works like a charm now.
Interface is there, firmware updated and I am happy as I can be.
I would like to thank you both for your help and assistance.
Kind Regards,
P.S. If any of you two passes through Linz, let me know. I owe you a beer or few.
