#beta test
#
# The algorithm is as follows:
#	If given -P flag, use that printer
#       Decide which printer to use by (minutes after hr modulo # of printers)
#	Assign states to printer
#	If printer is idle, use it
#	Look for idle printer
#	If found
#		use it
#	Look for busy printer
#	If found
#		use it
#	Look for stopped printer
#	If found
#		use it
#	Else all printers are disabled
# Printers can be in 4 states: 1==disabled, 2==stopped, 3==busy, 4==idle
