Other Configuration Manager-related features and issues
I was able to get it to work, but not perfectly. What I did differently is when setting up the new printer, I created a new TCP/IP port for each printer instead of selecting an existing port. Although I have so far created 5 copies of the printer, only 4 show up in Settings. so it's important to get the default settings correct while setting up the printer, because you might not get to see it again.
But all 5 do show up in my various software apps that I print from.
However, most of them do not pick up whether the profile is landscape or portrait, so creating different printers for those options may be a moot point.
I've been playing with this for a couple of hours now, so I'm about ready to give up and considerate a partial success.
