Under Windows is there a way for an admin to copy a limited account password from one machine to another?

I the admin of a home network with "home" version of Windows Vista and Windows 7. A Vista machine downstairs is connected to a printer. Now for other machines to access the printer, I understand that there must be a matching account (same username/password) on the "printer" machine, as home versions of windows can't remember login credentials.
