Unfortunately, if the user entered "TAPE" (or some device class/ldev
that resolves to being a tape drive), the process is hung until
an operator does a REPLY.

I tried doing:

   :listspf ; seleq [dev = foo]

to see if he could use LISTSPF in a sneaky manner, but listspf
fails to validate that the "device" is a valid device of any kind :(

Of course, if that bug were fixed (i.e., if the listspf "dev" was
defined to only allow valid printer classes)...then that would be
a workaround to the problem of identifying a valid printer class.
