remove_user_printer : 
    {Thy:string, Tyop:string} -> term_pp_types.userprinter option

SYNOPSIS
Removes a user-defined pretty-printing function for a given type.

LIBRARY
Parse

DESCRIBE
This removes a user-defined pretty-printing function for a given type (or family of types, generated by a type operator). If there is such a printer in the global grammar for the specified type, this is returned in the option type. If there is no printer, then NONE is returned.

FAILURE
Never fails.

COMMENTS
As always, there is an accompanying function temp_remove_user_printer, which does not affect the grammar exported to disk.

SEEALSO  add_user_printer
