Thanks for your information.
I have tried the three options from the support.microsoft.
Option 1= nothing changed.
Option 2 = It says map already exists.
Option 3 = after clicking Enter, a new line comes up asking for the username, giving the username and again Enter a new line comes up again asking for the username without any comment. ( like wrong name or not matching or ….etc )
I would expect the window to close as having accepted, but it’s not, I have to click it away which of course means that nothing has changed and the printer still doesn’t work.
What next ???
Thanks for your interest in my printer problem and for your help.
