Subject:    -6- What printers are supported under Impressario?
Date: 18 Aug 1994 00:00:01 EST

  This section lists two sets of device plug-ins: first, those bundled
  with Impressario itself, and second, those provided by third
  parties.  Impressario is an open architecture, and relies on third
  parties to provide support for devices which SGI cannot.  The
  Impressario Developer's Kit makes this easy.

  Devices supported in Impressario 1.1 (from the Impressario release notes):

      Apple LaserWriter Plus, II, IINT, IINTX, IIf, and IIg
      Hewlett-Packard DeskJet 500C, 550C, and PaintJet XL300
      Hewlett-Packard LaserJet IIP, IIP+, III, IIIP, and 4

  Impressario Version 1.2:

      Apple LaserWriter Plus, II, IINT, IINTX, IIf, and IIg
      Hewlett-Packard DeskJet 500C, 550C, and PaintJet XL300
      Hewlett-Packard DesignJet 650C.
      Hewlett-Packard LaserJet IIP, IIP+, III, IIIP, 4, 4P and 4L.

  All Apple LaserWriter printers must be connected to system using a
  serial port.  All Hewlett-Packard printers must be connected to the
  system using a builtin parallel port.

  Hewlett-Packard LaserJet II and III series printers do not work
  properly with less than 1.5 Mbytes of memory.  LaserJet 4 series
  printers require at least 4 Mbytes of memory.

  Apple LaserWriter IIf printers with less than 4 Mbytes of memory are
  not supported.

  Third Party Device Plug-Ins:

   ** The following printer manufacturers supply Impressario device
      plug-ins for some or all of their printers.  They are arranged in
      alphabetical order:

      As of July 1, 1994, SGI no longer resells printers manufactured
      by Tektronix, Genicom and Seiko. Tektronix, Genicom and Seiko can
      provide the Impressario device plug-in for their respective
      printers.

      All of the above device plug-ins have been tested and work under
      Impressario version 1.2.

      plug-ins for the following printers.  They are arranged in
      alphabetical order.

      Where third parties support the same printer that Impressario
      does, there are generally differences in how they are supported.
      For instance, some third parties support error-diffusion
      dithering, while Impressario does not.
