  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.

  12.     Modification history
  13.     7/23/92            TED            New file today
  14.     12/20/93        dmh            Sync'd with the shipping 1.0b3 GX driver.
  15.      6/23/94        dmh            Added overrides for renaming DTPs.
  16.      8/26/94        dmh            Sync'd with the shipping 1.0.1 GX driver.
  17.      6/14/96        cn            Updated to support Universal Interfaces 2.1.
