pdf导出不校验html标签,使用条形码（html、jpg或pdf）生成数据标签并打印（现在条形码不生成）...

试图解决一个链接到html条形码的问题。我需要做的是创建一个带有条形码的标签模板并发送到打印机。我选择使用html语言来创建带有输入数据的模板。我可以得到那个html，它看起来像这张图片。

然而，后来我试着打印html，我得到了标签，但没有打印条形码。所以我试着把它转换成pdf格式并发送到打印机，但每当我试图转换成pdf格式时，我都会在转换后的pdf中找到标签上没有条形码。

尝试使用一些不同的库(pdfkit,pdfcrowd,PyQt4.QtGui)，但没有使用条形码保存pdf。附加脚本：for index, row in output\_ramco.iterrows():

print row\['PARTNOMLT\_OUT'\]

htmlas = '''

@page

size: auto; /\* auto is the current printer page size \*/

margin: 3mm; /\* this affects the margin in the printer settings \*/
