Go to the CUPS page at <http://localhost:631/printers/> and click on the 
name of the printer to remove. At the new page there are two drop down 
menues. Click the one which reads "Administration" and select "delete 
printer" (or something similar - mine is talking German an I don't know 
the phrase used in the English version). Then you will have to enter 
your credentials, i.e. your user name (the one which is also in the 
lpadmin group) and the password for your account.
