Temporarily Disable Conditional Formatting when Printing

I'm after a macro to temporarily disable conditional formatting for a range of cells when printing.

Or even just temporarily set the cell background colour to "no fill" and then have it restored after printing.

The reason for this is I'm creating a bending schedule for steel reinforcement for concrete, and would like to warn the user that an invalid dimension has been entered using conditional formatting, however if the user really wants to continue I don't want the conditional formatting to show on prints, is this possible?

Many thanks.
