如何将完整的 Google 表格选项卡导出为 PDF，然后使用 Python 打印到本地打印机

问题描述 投票：0回答：1

几周后，我已经非常接近解决我的整体问题了。我希望将我的 Google 表格连接到本地打印机并打印标签“标签”和“声明”。标签需要打印 x 次，x 由单元格 f2 中的值定义。索赔也应该打印一次。

这似乎都已解决，但由于某种原因，完整的 Google 表格选项卡未正确导出为 PDF。

标签似乎是纵向打印的，当它应该是横向打印时，文本可能需要更大（下图是如何打印的）？

我似乎无法弄清楚如何调整它。 “索赔”选项卡只是打印空白，但我认为这对两者来说都是同一个问题。

关于如何调整此代码以完全打印选项卡的任何想法？添加示例 URL：

我想出了切换到横向，但标签仍然不正确。有没有办法将它们指定为 4x6？或以不同方式从 Google 表格导出？问题是标签没有按照 4x6 标签的格式导出为 PDF。

根据[ReportLab.Docs]: Graphics and Text with pdfgen - More about the Canvas（重点是我的）：

pagesize
参数 是两个数字的元组，以点（1/72 英寸）为单位。

页面大小被指定为元组，包括那些动态构造的（通过函数：e.g.：landscape）。
您可以看到这样的函数，例如从一个页面大小（作为参数传递）到另一个页面大小（返回）的转换。

这个也可以看源码：[ReportLab.HG]: hg-public/reportlab - (v3.5.0) src/reportlab/lib/pagesizes.py（我对Mercurial不熟悉所以我不知道 URL 是否永久（因为它包含 Id）或（如果不是，）它的有效期是多久）。

所以，必须把故障线改成：

label_canvas = canvas.Canvas(label_file, pagesize=landscape((6 * 72 * mm, 4 * 72 * mm)))

作为附加说明，我不知道最终尺寸应该是多少，但它们对我来说有点不对（因为 72 因子 - 代表 DpI）。
