使用Reportlab Canvas-如何创建一个选项来打印从浏览器本身生成的pdf？

问题描述

以下是使用Reportlab为我生成pdf的代码。

Here is the code which generates pdf for me using Reportlab.

现在，它只是在浏览器中显示pdf，并在共振中包含'附件'之后.header ['Content-Disposition']，它下载pdf。

Now, it just shows the pdf in the browser, and after including 'attachment' in the resonse.header ['Content-Disposition'], it downloads the pdf.

但我想要的是你在浏览器中的rint选项，它甚至允许你选择你的打印机。有可能吗？

But what i want is the rint option which comes you in the browser, which even allows you to choose your printer. is it possible ?

       data = "raghav"
       p = canvas.Canvas(self.response.out)
        p.drawString(50, 700, data)


        p.showPage()

        self.response.headers['Content-Type'] = 'application/pdf'
        self.response.headers['Content-Disposition'] = 'attachment;filename=testpdf.pdf'
        p.save()

推荐答案

根据你可以添加这两行来获得所需的结果：

according to http://blog.adlibre.org/2012/04/05/automatically-print-pdf-generated-reportlab/ you can add these two lines to get the desired result:

from reportlab.pdfbase import pdfdoc
pdfdoc.PDFCatalog.OpenAction = '<</S/JavaScript/JS(this.print\({bUI:true,bSilent:false,bShrinkToFit:true}\);)>>'
