推荐答案
这是 Windows 环境下的解决方案:Foxit！http://www.foxitsoftware.com/pdf/reader/
Here is a solution in Windows environement : Foxit !http://www.foxitsoftware.com/pdf/reader/
您可以调用foxit.exe(独立可执行文件)在后台静默打印PDF.
You can call foxit.exe (standalone executable) to silently print a PDF in background.
语法:foxit.exe/t "your file.pdf" "打印机名称"
Syntax : foxit.exe /t "your file.pdf" "The Printer Name"
shell = WIN32OLE.new('Shell.Application')
shell.ShellExecute("foxit.exe","/t "#{filename}" "#{printer}"")
