    As for printer noise, this is not likely the problem.  In the 
  infrared units there can be problems when printing if the battery is very low 
  but otherwise the problem should be limited to particular units if there is a 
  problem possibly with the printer itself.

 I think these were IR 
units in NC which is why I mentioned the old printer problem.  They 
are old units so the batteries are probably not what they used to be 
either.
