  many popular printers and scanners are provided.  The current WWW pages for

  PRINTING

  Impressario's printer drivers allow the user to control resolution, paper
  size, double-sided printing, text orientation, etc.  Impressario allows you
  to print many types of files (text and graphics).  See the question "What
  types of image files can Impressario print?" for details.

  Non-PostScript printer drivers utilize an Adobe(r) PostScript(tm) Raster
  Image Processor (RIP) to print image and PostScript files.  For Impressario
  2.0 and higher, this RIP is an extra-cost item.

  Impressario gives you full printer status in a network-transparent manner, so
  you can find out locally or from a remote system when the printer is out of
  toner, out of paper, has a jam, isn't turned on, etc.

  SCANNING

  Impressario also supports scanners.  The Graphical Scan tool allows you to
  scan data from a scanner, file, local or remote workstation display and send
  the data to a printer, file, or workstation display.  The Scanner
  installation tool provides a simple interface for installing and configuring
  scanners on your workstation.

  DEVELOPER'S KIT

  The Impressario Developer's Kit allows application and device plug-in
  developers to create software that fully supports printing and scanning in a
  manner that is consistent with the Impressario architecture.  This software
  is included standard with Impressario 2.0 and higher.

  FONTS

  The Impressario fonts subsystem contains 22 Type 1 PostScript fonts, which
  complement the base 13 fonts provided with Display PostScript. These
  additional fonts provide you with a complete set of industry standard fonts
  used in most PostScript printers.  In addition, these fonts can be used with
  the Display PostScript system to create true WYSIWYG applications.

  IMPRESSARIO 2.X

  Impressario 2.0 and higher is included standard with every SGI workstation
  and server.  In addition to supporting more PostScript printers, the 2.x
  releases provide a Kodak Color Management System interface that allows you to
  calibrate images you scan and print.

  Note that the PostScript RIP provided with Impressario 2.x is an extra-cost
  item not covered by the standard IRIX software license.  The PostScript RIP
  software is required for printing to non-PostScript printers.
