Are you creating these reports with Report vi's?
I can't say I've ever experienced the problem in LabVIEW, but I've certainly dealt with my fair share of printer problems before. Typically, if one thing goes wrong with one document in a printer, print requests will just queue up until it has been reset or until that magic button has been pressed to make the red light stop blinking. Most likely this is all that has happened in your case. If it happens again or if it is in any way reproducible, please post again!
If this is on a windows machine and you have scripting enabled, you can run a cscript and read WMI information that shows printer/queue status.
Here are some example scripts.
I can make an example when I'm at work tomorrow.
