通过 Python 从 Google 表格将二维码打印到标签打印机

Question

我有一个 python 代码，可以将“Claims New”选项卡打印到标签打印机。我的问题是，我能弄清楚打印内容的唯一方法是将所有内容都放在一个单元格中（如图所示）。我想要一个 QR 码也包含在我的 PDF 导出中。我似乎无法弄清楚如何调整此代码以便打印两个单元格（A1 和 A12）。不幸的是，我也无法将 QR 码与其他文本连接起来（使其成为一个代码）。

当前输出的是不包含二维码的PDF（只是A1单元格）。我想要的输出包括两个单元格（所以 QR 码在那里）。代码没有回溯，它运行它只是不包括所有需要的数据。

有什么想法吗？
