That's good, because that's what I was doing, just trying to get some ideas for you to try. You did a good job getting it sorted.
You did excellent research. You found something that I had overlooked in the manuals. I have four of them downloaded in pdf format. That is hundreds of pages. Getting it sorted was a matter of digging deep into the travel router configurations and the printer features. That is how I have learned the lion's share of what I know about computers.
Thanks again for your assistance.
