We currently lack 
  a ballot on demand printer that is capable of handling 18" ballots, but all 
  printers of this class can handle 17".  17" ballots are a nice feature in 
  their own right, being a standard paper size and all.  So, the request is 
  to add support for 17" ballots in GEMS and AVOS.
   
  This change 
  requires a firmware change which we will slip into 1.96.  Support within 
  GEMS artwork generation will follow, though there is no set schedule on this 
  yet.  The important this right now is to get the release into the 
  firmware so we don't miss the AVOS certification window.  If you have an 
  account that would like to use 17" ballots for whatever reason, give us some 
  warning and we'll do the GEMS update.  The changes required to GEMS are 
  trivial and mechanical.
