We also have the same issue, and I am sure its a new "feature" that some moron decided would be great and its yet another reason why we are migrating to a new platform.

So on this major design flaw I have found that you can set the printer to print both sides...if your printer has that capability. So at least your only using 1 sheet of paper. If you go to "Printer Settings" in QB and find the "Credit Card Receipt" do NOT make the mistake I did of unchecking both CUSTOMER and VENDOR options it will create an error message loop and you will need to use task manager to kill QB.

However well intended this feature is, it is actually a nightmare if you do not have a printer capable of double sided printing and what makes it worse is that if you unclick CC receipt printing you effectively crash QB. Intuit is a billion dollar venture...we all expect better.
