I think you are mixing up two things.
You mention that you turned on show reference plane. However I think you turned on show work plane.
In the screenshot hereunder I have a reference plane (1) and shown the work plane (2)
You can print out reference planes (with the setting in print menu). However (as far as I know) you can not print out work plane.
You can consider to create a grid with reference planes or for example use a grid or some other method.
If you think it would be beneficial, you can post your idea in the Revit Ideas section.

Please mention Revit version, especially when uploading Revit files.
You are correct. I was able to print the workplane grid in Revit 2013 but not in 2017.
Maybe you are using firefox? This happened to me sometimes when using firefox. Also some browser plugins might break the process
If it is a picture you try to upload, then you also can load it in you post directly

Enlint had a good workaround suggestion in his post on 9/6
Also, please consider posting to Revit Ideas
This is the method to use if you want to get a feature implemented (or perhaps restored) in Revit. Others can vote for your idea.
