Can I utilize preprinted 2023 W2/W3 forms with Quickbooks online? I switched to Quickbooks online mid-2023 and am not use to this system.

Thanks for dropping your concern here in the Community. Let me help you on how to change the setting for pre-printed forms inside QuickBooks Online (QBO).

To modify the setting for pre-printed forms when printing W-2s in QuickBooks Online, follow these steps:

1. In the Gear icon, click Payroll Settings.
2. Select the Form printing under preferences and decide how to print the forms.
3. Once done, hit OK.

On the other hand, I recommend scanning this article as your guidance to handle print issues for paychecks in the future inside QBO: Fix print alignment for paychecks. 

You can still reply to this post for more questions and clarifications with pre-printed W2/W3 forms inside QBO. I'm more than happy to assist you. Take care! 

Are you kidding?  What the hell is the matter with Quickbooks???  Per your suggestion, it DOES NOT ALLOW printing on the official (2 per page) W2's.  I know why.  Because you want to sell your forms at a ridiculous price.  QUICKBOOKS sucks.
