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