POLONO Bluetooth Shippping Label Printer (Open Box)

The headline says it all. The "driver" for windows runs automatically through the install stages, not manually as in their video. I wanted USB, but it detects BT available and pretty much insists on using that, even though it shows a USB connection (won't install if you don't give it BT). Finally installed. Tried a test print. Didn't print. With five tests queued up, somehow, one printed - the quality looked good, but since nothing else would ever print... Tried to use my Mac. Not seen as a USB printer. Tried downloading the printer app they suggest. It is really iPad only ... but sort of works on the Mac. Again, even though they insist you not try to configure it using BT on the Mac, the utility required BT. It finds the printer, and says it is connected, but never prints anything. Anyway, I don't want to use an app to print PDF files ... I want to print directly to the printer. Looks nice. Pity it doesn't work. Needs a LOT of work on driver and firmware - the usual failure point for Chinese devices. Returned.
