Booklet printing requires the Brother Print Support App. The standard driver doesn't support it.
Fix: Ensure the app is installed. Then, when printing:
- In your application's print dialog, select your printer and click properties.
- Go to Basic > 2-sided/Booklet.
- Select the booklet format option.
- Click the 'Settings' button to choose the binding type (four types available per orientation).
If that didn't work, you might be trying to use a paper size or media type that doesn't support 2-sided printing. Check the media type setting in the Basic section.
Heads up: Booklet printing uses 2-sided printing. Make your document's page count is a multiple of 4 for proper folding.
