          Appeal No. 95-3888                                                          
          Application No. 08/l05,244                                                  

               We find that the examiner had no reasonable basis for                  
          challenging the sufficiency of the disclosure and,                          
          accordingly, we will not sustain this rejection.  Clearly,                  
          from the instant disclosure, the blank boxes of the drawing                 
          constitute conventional microprocessors, printing mechanisms                
          and drivers.  The examiner contends that the printer must be                
          something more than conventional because the output of                      
          conventional printers is the printing on a medium.  Therefore,              
          concludes the examiner, it was not conventional for a printing              
          mechanism to provide control signals as disclosed and claimed.              
          We disagree.                                                                
               Conventional printing mechanisms include microprocessors               
          which, of course, output control signals.  More importantly,                
          however, the control signals output by the printing mechanism               
          here are simply signals for choosing the correct driver based               
          on the voltage level needed.  It is our view that it is                     
          unreasonable for the examiner to hold that skilled artisans                 
          would not have been able to cause a control signal from a                   
          microprocessor in a printing mechanism to be generated so as                
          to cause the selection of a particular driver based on a                    
          required voltage level.                                                     

                                          4
