Original size 1173 x 2051 pix @ 72 ppi - Required print size 201.60 x 351.00 mm

Open the Image -> Print Size dialogue. see: screenshot 1

The pixel size proportions and the required size proportions are not a perfect
match

The options - 

set the width to 201.6 height is a little off (352.5) see screenshot 2

set the height to 351.0 and the width is a little off (200.74) see: screenshot 3

You can break the link between x and y resolution and have 201.60 x 351.00 mm
This is ***never*** a good idea. It creates distortion in the image. see:
screenshot 4
