      w20-575-44:~> lpq -Pajax

       TypeError: coercing to Unicode: need string or buffer, NoneType found    

Further investigation reveals:

consult / printing / ezyang  16:37  (Edward Z. Yang)                         
       >>> from debathena.printing import common                                
       >>> common.find_queue('ajax')                                            
       (0, None, 'ajax')   

       >>> from debathena.printing import common                                
       >>> common.get_cups_uri('ajax')                                          
       u'file:///dev/null'                                                      
       >>> common.canonicalize_queue('ajax')    

       (yes, that last line is blank)                                                                                                

Further investigation is necessary to determine if this affects Jaunty, or just w20-575-44.
