Hello there, @LauraMay117.
Thanks for joining the thread. Let me help confirm this information about printing W-2.
Yes, you're right, starting today QuickBooks will allow you to print on a 3-part perforated paper. For more information about the compatible window envelopes, you can check out this helpful article: https://community.intuit.com/articles/1763397-about-paper-and-envelopes-for-form-w-2.
I'd like to thank everyone for bearing with us about this issue. Please know you can always reach me and my colleagues in the Community if you have other questions. Have a good one.
