Hi, Jlindsay.

Thanks for reaching out to the QuickBooks Community. First I wanna say, you did a great job on troubleshooting so far. I have a couple of tips that will assist in getting this resolved.

When running the QuickBooks Tool Hub each tab is related to a specific problem. I understand you may have run the PDF Print and Repair tool. Have you tried running the Install Diagnostic Tool, as well? If after running that tool, you're still experiencing crashes when certain users are printing, I would urge you to use this article: Unrecoverable Error in QuickBooks.

I've always found that article as a great help to me to resolving errors. Please let me know how it works for you and if you need any assistance. I'm only a reply away.
