Good morning, @nzaczkowski. 

Thanks for reaching out to the QuickBooks Community. How are you doing today? 

To clarify, does this only happen to the user at one workstation or all of them? If another user signs in at the same workstation, does the same thing happen to them? 

If this only happens to one user at all workstations, it could mean that you have a broken user. To resolve this, you'll need to delete the broken user and add them back. This will not affect any data in the company file. I'm including some steps below to walk you through the process. 

To delete the user: 

1. Sign in as the company admin.
2. Go to Company, then Users, and choose Intuit Account User Management.
3. Click the user, then select Delete from Action.
   Note: You can search for a user with their name or email address in the search bar. You can select the email or status column to sort and find a user.
4. Hit Delete user to confirm the deletion.

To add them back:

1. Go to the Company menu, then choose Users.
2. Select Set Up Users and Roles.
3. Enter the admin password, then hit OK.
4. Click the User List tab, then select New.
5. Enter a username and an optional password.
6. In the Available Roles section, select the user’s roles, then select Add.
7. Hit OK.

Once the user has been added back, let's go ahead and have them print another invoice. Please let me know how it goes. 

For more information about this process, check out the help guides I'm including below.

Don't hesitate to let me know if you have any questions or concerns. I hope you have a wonderful rest of your day!
