Cannot reset printer correctly.

Initially I had an HP Deskjet 5550 on USB #1.
Now when I want to install another HP Deskjet I cannot get it to print.
i.e. via localhost:631 I can delete and add the correct printer BUT USB #1 always shows as "USB #1 (hp deskjet 5550)". Even after deleting.

So, to keep the new printer alive with beh, I have to add the identifer usb://Deskjet5650?Serial=MY82Z6711Q1
This is from the 'old' 5550 so the new printer refuses to play.
Probably because the new printer does not have this serial number?

If I plug in the 5550 it still tries to work.
How do I remove this 5550 ?serial number and get back to usb:/dev/usb/lp0?
