Had a Brother P-Touch label printer, a 1230PC, one that prints from my PC. I bought it years ago and hadn't used for a while. Got it out of the cupboard and tried to use it, but I got a "communications" error. So I assumed it was broken, and purchased a new one. A P-Touch P700. Only to get exactly the same error message when I tried to print.
The internet told me what that "error" message actually meant was that I was trying to use a "non-genuine" tape cartridge in it.
There's not even that obscure warning on the Brother labeller. They don't even have the honesty to tell you that's the problem in the error message. I see people like InkStation selling "compatible" tape cartridges, listing them as suitable for my P-Touch model. I now don't know whether I might be throwing more good money after bad, and wasting my time, if I buy some of them. Does anyone know? I thought Brother was pretty good with stuff like using "non-genuine" toners and ink.
(To really annoy me when I was already pretty annoyed, the Customer Contact Form on their web site doesn't work, preventing me from simply complaining, meaning their phone support got an earful of what I thought.)
Does the box or manual say genuine cartridge must be used?
Unfortunately I think most people do realise the printers often require genuine cartridges. The industry is similar to pod based coffee machines. The machines are cheap to get you locked in and then the margins on the consumables are huge.
