I have an odd problem that's been affecting some of my templates for the past few years that I really can't seem to figure out. I use an XY Scatter plot to plot 3-8 data points and then apply a 3rd order polynomial trendline to it. The worksheet is then printed to PDF or directly to paper. On some of my users computers the Trendline does not print. It shows in the print preview, but not on the page or in the PDF. This is happening in a template (saved as .xltx) on only some users computers. We all use different versions of Excel, however this issue isn't arising on one specific version or another. Additionally, the same file can be opened by a different user and then printed properly. All of this leads me to believe it is a user settings issue, however I cannot for the life of me figure it out, nor can I find any information online.
