//	  + : Added in the description of a label :
//		font-size	: defaut char size (can be changed by calling Set_Char_Size(xx);
//		paper-size	: Size of the paper for this sheet (thanx to Al Canton)
//		metric		: type of unit used in this description
//				  You can define your label properties in inches by setting metric to 'in'
//				  and printing in millimiter by setting unit to 'mm' in constructor.
//	  Added some labels :
//	        5160, 5161, 5162, 5163,5164 : thanx to Al Canton : acanton@adams-blake.com
