推荐答案

你无法通过服务器代码在客户端计算机上打印，您只需向用户提供文件\page，如果他们想打印它们，他们就会。如果网站可以强制文件到您的打印机，那么每个其他网站都会通过广告和优惠券向您的打印机发送垃圾邮件。

You can't print on the client machine from your server code, you have to just give the user the file\page and if they want to print it they will. If websites could force documents to your printer then every other website would be spamming your printer with adverts and coupons.
