Print.js: Base64 Pdf on firefox

[PabloSzx]

Hello, currently the library doesn't support printing pdf in firefox, but there is supposed to be working that instead of printing the pdf, it opens in a new tab, well, appareantly it doesn't work if you are trying to use a base64 pdf string with the latest release v1.0.55

It gives me:

TypeError: window.open(...) is null

Hey Pablo, thanks for reporting this.

The base64 option is a new feature that just got added. I honestly didn't think about the unsupported browser scenario when implementing this. It needs to be handled.

I needed a workaround, i got it working this way if someone else needs it.

_pdf_ is the base64 encoded pdf string

printjs({
      printable: new Buffer(pdf, "base64"),
      type: "pdf",
      base64: true,
      fallbackPrintable: `data:application/pdf;base64,${pdf}`,
});
