LibreOffice 6 impress keeps changing format to landscape when trying to print

I have an impress document that I am trying to print. I have tried several times to print the slides in portrait orientation, but it keeps reverting to landscape. I have tried changing it under the file->print tabs, file->printer settings tab, and on the printer base settings in windows. I had this problem on my previous edition of libreoffice as well and updated to 6.0 tonight in hopes it would be fixed. I searched the forums and tried the workarounds previously mentioned, but they did not seem to work for me.

If it is relevant, I am using a HP pavilion running Windows 10, and the printer is a HP OfficeJet pro 8600 Plus.

If any of you know how to fix this, I would really appreciate it. Thanks.

What paper format you have trouble with?
