As of now, printing the Form 1099-B isn't possible in QuickBooks Online (QBO), @wsj333.

Rest assured I'll point you in the right direction so you can print your Form 1099-B. 

You can consider using our Intuit TurboTax to file your form as suggested by my colleague Rasa-LilaM above.

Additionally, you can also send your feedback to our product engineers. This way, they can review your suggestion and might consider adding it in the future updates. 

Furthermore, I'm attaching this article that you can read for reference in printing your other 1099 form: Print your 1099 forms.
