depends on the printer...but there's no reason that the initial password
cannot be all numbers also, and also keyed in from the op panel.
then you can use that password to authenticate to the printer's web server.
or if you prefer, you can restrict usernames and passwords to all digits.
(though you would want to allow for long passwords - say 20 digits - so
that they would have enough entropy to thwart brute force search attacks)
