Thanks for your reply!

It was easier than I thought!

def checkImageOrentation(path):
    files = glob.glob(path + '*.jpg')
    for f in files:
        print('file is', f)        
        original = cv2.imread(f)
        decodedObjects = pyzbar.decode(original)
        # decodedObjects[0][2][0] is the top left x value, should be about 667
        # if it is less than 500, the page must be upside down, rotate the image
        if decodedObjects[0][2][0] < 500:
            rotateImage(original, f)

decodedObjects[0][2][0] is the top left x value of the QR code.
If the page is the right way up, decodedObjects[0][2][0] should be about 667, depending on the printer.

If a page is upside down, decodedObjects[0][2][0] is only about 47
