  22  * This module implements support for gathering and comparing available
  23  * printer information on a SVID or XPG4 compliant system.  It does this
  24  * through the use of the SVID/XPG4 command "lpstat(1)".
  25  *
  26  * The expectations is that execution of the command "lpstat -v" will
  27  * generate responses in the form of:
  28  *
  29  *      device for serial: /dev/term/b
  30  *      system for fax: server
  31  *      system for color: server (as printer chroma)
