Hi there, @tradecfo. It's good to know that you've updated everything on your end. I'm here to help ensure you'll be able to print your 1099-NEC in QuickBooks Desktop (QBDT).

Since the issue still persists, let's rename the Qbprint.qbp file to resolve printing issues.

Here's how:
 

1. Find the QbPrint.qbp file.
2. Right-click the QBprint.qbp file for your QuickBooks version and select Rename.
3. Add the word old to the file name. Example: QBPrin
4. Open your QuickBooks Desktop.
5. Go to the File menu, then select Printer Setup.
6. Select an invoice transaction in the Form Name list and select OK. This will create a new QBprint.qbp file. 

Once done, try to open and print the forms again. 

You can check out this article for more information: Rename the Qbprint.qbp file. 

I'm also adding this article that contains additional information on how to fix printing issues: Troubleshoot Issues with Printing and .PDF Files. 

Let me know in the comment below if you require further assistance in printing 1099 forms. I'd be glad to help. Take care and have a great day!
