Is it in a .jpg format (picture format)? If so, did you try choosing to print full page? Not sure what else to do, but you can search for templates and should be able to find one that's in a PDF document.
You don't have to refrigerate your royal icing, but it is best not to store it for too long in the bottle or bag. It tends to separate. That's the biggest issue I have with cookies! I want to be as organized as possible since it always seems like such a huge undertaking, but I haven't figured out how to mix and store all my icing without constantly filling bags and cleaning tips!

I think it was just an off day!

Good news! I heated up more cream and added it to the ganache. I had to heat the ganache in the microwave for several bursts, but it all came together wonderfully and was the right consistency! I didn't have to eat batch one with a spoon all by myself after all! LOL!
