Users posting in this thread seem to want different things. For example, @robertpaulson and @metoo are looking for a “temporary”/one-time version of the Master Password to use when one does not feel secure entering the “real” Master Password. There is a separate Feature Request for that exact functionality: Temporary Master Password, so posts supporting such a feature should probably be posted there, not here.
Others who have posted in this thread seem to be asking for recovery codes for 2FA, which is a function that already exists, as pointed out by @Cjkeenan above.
That leaves only OP, who seems to want a printout of codes that can be used as a substitute for a forgotten Master Password. The obvious question (“why backup access codes printed on paper are better than printing your master password on a piece of paper”?) was asked by @dh024 and @Cjkeenan, but so far there has been no clarification of this.
