emacs -Q <RET>
M-x calendar <RET>
M-x cal-tex-cursor-day <RET>
M-x tex-buffer <RET>
 ---> Buffer is not associated with any file
M-x tex-print <RET>
 ---> No appropriate ‘.dvi’ file could be found

However, if the buffer 'calendar.tex' is saved to a file then we
can proceed using M-x tex-compile <RET>, etc.

Perhaps the user might be given instructions at the head of the buffer
'calendar.tex' that are different from those presently seen.

Best wishes,

tex-buffer is supposed to support this usage:
  "Does not save the buffer, so it's useful for trying experimental versions."

However, it seems that this does not work since Emacs 22.1.

A quick bisect points to b2272f6.

Thanks. tex-mode.el of 2007 is a long time ago!

This should now be fixed in Emacs 28.

Yes, I can confirm this. Thank you.
