Hi,
Thank you for writing to Microsoft Community Forums.
I understand that you receive an error, ‘Print Unable 04’ when trying to use your Brother printer. I’ll certainly assist you with the issue.
We would like to know the version of Windows installed on the computer. To check type: winver in the search bar on the Taskbar and hit Enter.
The error "Print Unable 04" indicates that a hardware malfunction has occurred. I would suggest you to refer the troubleshooting steps mentioned in the article "Print Unable 04" and see if that helps.
Let us know how it goes.
Regards,
