为了能够使用户在下载系统Server生成的PDF文件后，自动打印。有一些第三方软件是可以直接打印PDF，但都需要购买。所以，写了下面一段Script，并且主要解决与客户端AcrobatReader的安装目录无关。
@ECHO OFF
ECHO Usage: PRINTPDF pdf_file
ECHO.
ECHO Where: "pdf_file" is the name of the PDF file to be printed.
ECHO.
ECHO Notes: This batch file works only if PDF files' default association is any
ECHO Acrobat Reader version.
ECHO Modification of the code to check for valid association by Chuck Hicks.
ECHO Modification of the code to enable long file names by Michael Lintner.
