You do need to plug into alternate power or use they're proprietary rechargeable battery for wireless printing. No big deal, would you really expect AA battieries?
Best brother label maker yet, as I can use with iPhone or iPad.
I've had 2 pc connected and 2 free standing units.
Great investment
Powerful professional labeler with lots of software and connectivity options
Professional labeler works great with Windows software and IOS app for cables. The NFC function does not work with IOS, only Android. Its not difficult to setup a direct wifi connection between the app and the printer, or from Windows with a wireless network. The USB wire works fine from Windows PC. The software requires some getting used to. The BT versions are more flexible in connectivity than the W versions.
I already have two other brother p-touch label makers, however this one is great! With the computer or mobile app you can customize the label with clip art, pictures and different fonts, as well as bar codes.
