使用 Nodejs 打印 Base64 字符串？

Question

I used the html2pdf npm package to send a base64 string of a pdf to my nodejs server. I then use Nodemailer to send that pdf to an email address setting nodeMailer property like:

let mailOptions = {
        from: '"Nodemailer contact" <foo@example.com>', // sender address
        to: 'abc@gmail.com', // list of receivers
        subject: 'Node contact request', // Subject line
        text: 'Hello world?', // plain text body
        html: output, // html body
        attachments: [{
            filename: 'new.pdf',
            content: encodedpdf,
            encoding: 'base64'
          }]

    };

Now, I also want to print this PDF that is encoded Base 64 string to a windows printer using Nodejs. I have tried googling a way to do this but could not find anything useful.

There is a node-printer but I believe it does not support the latest Node. I used it once in the past and it kinda worked. It's supposed to work on Windows. In order to print a PDF, you need to convert it to EMF format and then you can print it . Although there is a node-podium package which simplifies that, it's apparently not maintained anymore.

You might get more luck in installing some command line tools and calling them from Node.
