It works now!!! :-D
Thank you all very very much!
It also turned out that I got quite a bit of old jobs queued there... quite a mess.
So I needed to read a litle on those queue management commands ... pdisplay and pdelete, but also psetup and pgo since (don't know why) one of my past hellocob attempts triggered an 'IQ40A' message and was stuck on the lst queue.... overall, I managed to clean all up, and jobs started to run an print nicely...? a ton of fun!!!
Cheers.
