         PRINTER_PAPER_FORMAT:
         specifies a predefined paper format, set value 
         to PRINTER_FORMAT_CUSTOM if you want to specify a custom format with 
         PRINTER_PAPER_WIDTH and PRINTER_PAPER_LENGTH. value 
         can be one of the following constants.
       
           PRINTER_FORMAT_CUSTOM:
          let's you specify a custom paper format. 
         
           PRINTER_FORMAT_LETTER:
          specifies standard letter format (8 1/2- by 11-inches).
         
           PRINTER_FORMAT_LETTER:
          specifies standard legal format (8 1/2- by 14-inches).
         
          PRINTER_FORMAT_A3:
          specifies standard A3 format (297- by 420-millimeters). 
         
          PRINTER_FORMAT_A4:
          specifies standard A4 format (210- by 297-millimeters).
         
          PRINTER_FORMAT_A5:
          specifies standard A5 format (148- by 210-millimeters).
         
          PRINTER_FORMAT_B4:
          specifies standard B4 format (250- by 354-millimeters).
         
          PRINTER_FORMAT_B5:
          specifies standard B5 format (182- by 257-millimeter).
         
          PRINTER_FORMAT_FOLIO:
          specifies standard FOLIO format (8 1/2- by 13-inch).
         
        PRINTER_PAPER_LENGTH:
        if PRINTER_PAPER_FORMAT is set to PRINTER_FORMAT_CUSTOM, 
        PRINTER_PAPER_LENGTH specifies a custom paper length in mm, 
        value must be an integer.
       
        PRINTER_PAPER_WIDTH:
        if PRINTER_PAPER_FORMAT is set to PRINTER_FORMAT_CUSTOM, 
        PRINTER_PAPER_WIDTH specifies a custom paper width in mm, 
        value must be an integer.
       
        PRINTER_SCALE:
        specifies the factor by which the printed output is to be scaled. 
        the page size is scaled from the physical page size by a factor 
        of scale/100. for example if you set the scale to 50, the output 
        would be half of its original size. value 
        must be an integer.
       
        PRINTER_BACKGROUND_COLOR:
        specifies the background color for the actual device context, 
        value must be a string containing the rgb 
        information in hex format i.e. "005533".
       
        PRINTER_TEXT_COLOR:
        specifies the text color for the actual device context, 
        value must be a string containing the rgb 
        information in hex format i.e. "005533".
       
        PRINTER_TEXT_ALIGN:
        specifies the text alignment for the actual device context, 
        value can be combined through OR'ing the 
        following constants:
       
          PRINTER_TA_BASELINE:
          text will be aligned at the base line.
         
          PRINTER_TA_BOTTOM:
          text will be aligned at the bottom.
         
          PRINTER_TA_TOP:
          text will be aligned at the top.
         
          PRINTER_TA_CENTER:
          text will be aligned at the center.  
         
          PRINTER_TA_LEFT:
          text will be aligned at the left.  
         
          PRINTER_TA_RIGHT:
          text will be aligned at the right.
