Can you post which version of GridView you're using? We'll see what we can find.

I have to admit, we have not spent much time on GridView printing, as we assumed that users were sending the results to Excel.

After a little testing, I bet you'll find that the workstations are using different default printers.

If you choose a specific printer for the View, then you'll find that the orientation will stick. When I changed the default printer for the workstation, then the View reverted to the default orientation for the default printer.

We'll discuss whether that's the behaviour that makes sense. I'm not sure it is.
