Hi,

asking for passwd seems to be a new "feature" of cups (i would call it a 
bug)

You have to modify your printers.conf for this printer, there should be 
lines beginning like

AuthenticationRequired
AllowUser

for this printer entry. Comment them out:

shut down cups    #systemctl stop cups

edit the file /etc/cups/printers.conf comment the lines out

restart cups	#systemctl start cups

...
there should be a more elegant and compatible way of doing this and i 
believe there is a general switch in /etc/cups/cupsd.conf or somewhere 
else to change the security level to prevent these entries, but i didn't 
find it.
