    值为2---横向打印，固定纸张；  
    值为3---纵向打印，宽度固定，高度按打印内容的高度自适应；
    0(或其它)----打印方向由操作者自行选择或按打印机缺省设置。
    intPageWidth：
    纸张宽，单位为0.1mm 譬如该参数值为45，则表示4.5mm,计量精度是0.1mm。
    
    intPageHeight：
    固定纸张时该参数是纸张高；高度自适应时该参数是纸张底边的空白高，计量单位与纸张宽一样。
    
    strPageName：
    纸张名，必须intPageWidth等于零时本参数才有效，有如下选择：
    Letter, LetterSmall, Tabloid, Ledger, Legal,Statement, Executive, 
    A3, A4, A4Small, A5, B4, B5, Folio, Quarto, qr10X14, qr11X17, Note,
