Connect a Brother HL-2040 Series Printer to a Airport Express.

Chances are, you already know how to connect the printer to the USB port on the AirPort Express.

What you really may be asking is how to configure things so that you can print this way.

On your Mac....

Open System Preferences (gear icon on the Mac's dock)

Open Print & Scan

Click the + button at the bottom of the printer list

Hopefully, your printer will appear after a scan for printer drivers

If yes, click the name of the printer to highlight it

Click Add at the lower right

Try to print. If you have previously configured the printer to work when connected to your Mac, you actually have two "locations" for the printer now installed, so you must choose the correct "location" when the print dialog box appears.

Using the Print & Scan box, you can also designate the printer connected to the AirPort Express as the "default" printer, so you won't have to choose which printer to use.

If your printer does not appear after a scan for printer drivers, you might try contacting Brother support to see if they possibly have a printer driver that you could download and install to enable the feature that you want.

If you still cannot print, you should understand that not all printers are compatible when connected to the USB port on the AirPort Express, so that may be the case here.

You need to install an App like Print Central on the iPad to see if that will allow printing. No guarantees, but it is probably worth a try if you need to print from the iPad.
