Since A4 is almost exactly 210x297mm, the size 216x316 is somewhat odd. I found some use of that size in some European notebooks, but nothing official.
However, no matter on what size paper you print on, the size and shape should come out exactly what you want, providing that the ink area will fit on the paper.
So what's the problem? I can't tell, since you are not telling me what you are using to print with, the software, that is. And even if your told me, I may not be able to know, or find out what controls there are that control the hardcopy output. You did say one thing though, and that is "I dont select fit to page option."
From what you mention, that is the sort of control that you DO NOT want to use, and you say you aren't... but is that what you are getting? I can't tell. But it sounds like you may be getting the size distortion you thought you shut off.
Look into that more. If other people are getting the print results you want, then see what they are doing that is different.
I can't help much more that that. Sorry, and good luck.
