Final print size does not match screen view.

Question

Hi
I am having problems getting my final prints to match the screen view.  Most recently I have had this problem:  I have an image that is sized to 5X7.  I have it on a 5X7 template in the print module of Lightroom.  The image dimensions in Lightroom say 5X7.  I print on 5X7 paper (I actually measured it to be sure).  ON the screen they look perfect, match the the templates and measure out fime with the onscreen rulers.  Without fail a portion of the print is cut off on the final print.  The long side of the print is the most effected.  This is not just limited to 5X7's, it happens across the board.  Is this a common problem or I am I doing something wrong?  In the 5X7 example above the print comes out 5.2 X 7.3 give or take.  I am using Lightroom 5.3 on an iMac running OS 10.9.1.  The printer is a Canon Pro 100. 
I welcome any help with this.
Thank you
Joe

If the problem is that the printed image is being scaled larger, this is a very common side effect with borderless mode settings in print drivers. Typically, (though sometimes you can prevent this where alternative borderless options are given) - an extra unrequested scaling % ensures that any physical mis-registration or inaccuracy of the paper size, does not leave any accidental white edges.
That's nothing to do with LR's end of the process, if so.
