#=======================================================================#
# OPTIONS RECOGNIZED: ( all may be preceded with a "-" )		#
#	NOTE: Options marked with a "*" before their descriptions	#
#	      are provided for backward compatibility with the		#
#	      former hp2225a, hp2227a and hp3630a printer models -	#
# 	      these models have become links to this model. Consult	#
#	      your printer reference manual to determine which		#
#	      options are valid for your particular printer.		#
#									#
# Horizontal Pitch Selection:						#
#	c  		compressed print mode				#
#	e  	      * expanded print pitch				#
#	10 	      * 10 cpi (Pica print pitch)			#
#			  (expanded compressed on thinkjet and quietjet)#
#	12 	      * 12 cpi (Elite print pitch)			#
#									#
# Print Quality Selection						#
#	q | lq 	      * near letter quality				#
#									#
# Font Selection							#
#	b | bold      * set font stroke weight to bold			#
#									#
# Output filtering: (Default Cooked)					#
#	r | raw		raw mode for plotting mode etc.			#
#									#
# Other:								#
#       nb		do not output banner page (to save paper)	#
#									#
#		NOTE: * = NOT OFFICIAL PCL LEVEL 1 OPTIONS, USE OF	#
#			  THESE OPTIONS MAY OR MAY NOT PRODUCE		#
#			  DESIRED RESULTS.				#
