 The utility is intended first of all for the managers of NT networks,
 it is necessary to them to set to the printer some intervals of availability.
 For example: the chief has put a task - printer should not work in holidays.
 Per working days should work under the following circuit: 9-00 - 11-00 prints, 
 11-00 - 14-00 does not print, 14-00 - 19-00 prints, 19-00 - 9-00 does not print.
  To realize such circuit by means NT it is not obviously possible, but with use 
  of the given utility and sheduler - no problems.
 The task can seem far-fetched, but it is the severe truth of life.
 I shall be very glad, if this software will be useful.
Usage:
	1. Enumerate printers: prnctl.exe \\servername
		result - shows all shared printers on \\servername
	2. Get printer status: prnctl.exe \\servername\printername status
		result - shows printer status
	3. Stopping printer: prnctl.exe \\servername\printername stop
		result - printer printername is stopped
	4. Pausing printer: prnctl.exe \\servername\printername pause
		result - printer printername is paused
	5. Starting printer: prnctl.exe \\servername\printername start
		result - printer printername is resuming
	6. Purge printer: prnctl.exe \\servername\printername purge
		result - printer printername is purged
	7. Setting printer as default: prnctl.exe \\servername\printername default
		result - printer printername set as default printer on workstation,
		if printer does not exist at workstation, it will be connected
