Printing landscape only with PDF files

[#1]

My printer prints landscape whenever I try to print a PDF file.

No problem with a word file. 

It doesn't seem to be a problem with the printer (Driver) because the same problem happens with two different printers.

Must be computer-based - Microsoft Surface Pro.

What do I do to fix the PDF problem?

Thanks,

Gary

How are we supposed to know? What can you tell us about your printer, the driver settings the print settings in Reader and Word?
