You've gone this far so you could do

  sudo apt-get --purge autoremove

to clean up other packages which are not needed now.

I'll also point out (before anyone else does) that, if you have a need
for scanning, some readjustment will be now be needed. Anyway, one thing
at a time. Back to printing.

Ok, you didn't actively install a USB print queue but you did have a
USB connection and, in that situation, Ubuntu will automatically set an
IPP printer up for you. Many users would appreciate that facility. I
hope you have disconnected the printer from the USB port.

I use Debian, but its printing system and that of Ubuntu are identical
for all intents and purposes. However, I am unfamiliar with the two
interfaces you refer to. If the Ubuntu interface is based on GNOME I can
think of a reason. Would you describe what you see there *immediately*
after restarting cups-browsed.

It is essential to restart cups-browsed. Does 'lpstat -t' also show these
three printers? Please post the output if it shows more than 1.

That's the good part, isn't it?
