Its a known issue.  There was a pop-up alert in the program last week? sometime.

You can try the things mentioned in the article.  Ive discovered that when it crashes once, it will continue to do so every time I try to print unless I reboot my computer, then I'm good for a few more hours

You can print to PDF then open the PDF outside of the program, that works for me as well, when I have a client sitting there and I just need the signature pages to print and I don't want to reboot my whole computer.

Be sure to set your automatic back up for a short time frame (I have it set for 1 minute), that way you wont lose any client data if it happens when you're printing something out on the fly in the client file and you haven't saved it yet!   My program has always recovered the client file after a print crash.
