How to test print page on Brother printer?

To print a test page on a Brother printer, you can usually hold down the "Go" button or a similar button for a few seconds until the test page prints. You can also check the printer manual or Brother's website for specific instructions for your printer model.

How about providing us with the exact model name/number of your Brother printer?

If your printer did not come with a user manual, have you tried contacting Brother support for assistance yet? ... or just did a search on the Internet on this printer? You mention that you couldn't find any instructions, but we have no idea what or where you searched.

That is normally done in the printer admin menu, not from your Apple device.
