' Abstract:
' prnmngr.vbs - printer script for WMI on Windows 
'     used to add, delete, and list printers and connections
'     also for getting and setting the default printer
'
' Usage:
' prnmngr [-adxgtl?][co] [-s server][-p printer][-m driver model][-r port]
'                       [-u user name][-w password]
'
' Examples:
' prnmngr -a -p "printer" -m "driver" -r "lpt1:"
' prnmngr -d -p "printer" -s server
' prnmngr -ac -p "\\server\printer"
' prnmngr -d -p "\\server\printer"
' prnmngr -x -s server
' prnmngr -l -s server
' prnmngr -g
' prnmngr -t -p "printer"
