# SNMP monitoring of printmib compliant printers
# $Id: printmib.monitor,v 1.1.1.1 2005/02/18 17:52:24 trockij Exp $
# Added changes as per information from Andrew Ryan
# fixed bug where it would not return error if the device was not a printer
# or was not responding to snmp connects
#
# returns 1 if problem with printer
#
# Seth Vidal (skvidal@phy.duke.edu)
# many portions of this code were hacked out of hpnp.monitor
# newer hps don't support the oid specified in hpnp so I wrote this to watch
# them - it should work with almost any printmib compliant printer
