  4.     OldApp.c
  5.     This file implements old application message overrides for the specific driver.
  6.     
  7.     Included in this file is the old PrintRecord emulation.  Note that the ImageWriter
  8.     PrintRecord is a wonder of misdirection and special cases.  You'll have fun
  9.     figuring out the code - so unless you really want to exactly emulate the ImageWriter
  10.     pages, you shouldn't spend too much time looking at this code.
