   5 // Class to print labels in Avery or custom formats
   6 //
   7 // Copyright (C) 2003 Laurent PASSEBECQ (LPA)
   8 // Based on code by Steve Dillon
   9 //---------------------------------------------------------------------------------------------
  10 // VERSIONS:
  11 // 1.0: Initial release
  12 // 1.1: + Added unit in the constructor
  13 //      + Now Positions start at (1,1).. then the first label at top-left of a page is (1,1)
  14 //      + Added in the description of a label:
  15 //           font-size : defaut char size (can be changed by calling Set_Char_Size(xx);
  16 //           paper-size: Size of the paper for this sheet (thanx to Al Canton)
  17 //           metric    : type of unit used in this description
  18 //                       You can define your label properties in inches by setting metric to
  19 //                       'in' and print in millimiters by setting unit to 'mm' in constructor
  20 //        Added some formats:
  21 //           5160, 5161, 5162, 5163, 5164: thanks to Al Canton
  22 //           8600                        : thanks to Kunal Walia
  23 //      + Added 3mm to the position of labels to avoid errors
  24 // 1.2: = Bug of positioning
  25 //      = Set_Font_Size modified -> Now, just modify the size of the font
  26 // 1.3: + Labels are now printed horizontally
  27 //      = 'in' as document unit didn't work
  28 // 1.4: + Page scaling is disabled in printing options
  29 // 1.5: + Added 3422 format
