Blue tooth Printer set up problems

totally wild guess,based on a vast fund of ignorance. I gather from failed attempts to introduce my cellphone to the hands-off function in my car that Bluetooth is a finicky critter that wants a formal protocol precisely performed before it will give the original handshake, and then can be nervous. It's quite a short-range protocol; are your printers within range? And did removing all the printers from the installation mean they now feel jilted and want the introduction ritual re-executed before they'll talk to each other again?

Since no one else seems interested in helping out, maybe this will give you possibilities to consider.
