为什么PDF中的文本字符叠加在一起？

标签： php pdf text fpdf letter-spacing

我正在使用FPDF创建PDF。 PDF可以95％的时间呈现到网页。有时，PDF将呈现到页面，所有文本字符左对齐，但堆叠在彼此之上。好像字母间距设置为零！

当我右键单击网页并从“右键单击”菜单中单击“打印”并打印PDF时，同样的事情发生了，但是所有的时间.....然而，当我保存PDF到我的桌面，并打开它打印，PDF将打印正常所有的时间！为什么？？我已卸载，然后重新安装我的打印机\驱动程序两次。我没有尝试从不同的打印机/计算机打印...此外，我确实有一个备份副本，我知道从2017年12月18日没有这个问题，它仍然使用该副本也是如此....
