Lightroom :: Change Printer Settings Without Printing?

To create a new template one has to go through the "Printer..." dialog to change the paper size. Unfortunately, the only way to actually SAVE the new settings is to click OK, which causes Lightroom to print the current image.  In all other programs, the "Printer..." dialog is used only to adjust settings.  In Lightroom it seems to serve as a "Print" dialog as well.  On Windows this violates long-standing UI function guidelines embodied by pretty much all other software.
 
A concrete example:
 
I needed to create a new template to print on 8-1/2 x 11 paper.  To do so, I created a new template while in an existing template for 8x10. This copies the settings to the new template, but one cannot adjust the cell size to anything larger than 8x10.  So I went to the "Printer...:" dialog to change the paper size.  However, when clicking OK on the "Printer..." dialog, to save the new paper size, Lightroom starts printing the current image.
 
What should happen is that the settings are saved and no printing starts.  Printing should occur only when I click on "Print".
 
Unless I've missed something and there's a way to change paper size, color profile, paper type, etc. (all the things you can change on the printer driver's dialog) from within Lightroom without invoking "Printer..."?
