Sticker Bluetooth Test
Throwaway test for the AiYin IP-486BT. Open in Chrome on Android or Windows. Not the real tool.
1. Connect
Status: not connected
2. Sticker size (match the roll in the printer)
3A. Small sticker: printer barcode command (TSPL)
Fastest and sharpest. If nothing prints, try 3B.
3B. Sticker as an image
Works even if the printer does not understand TSPL text. Chinese text goes this way.
Big sticker (use lines 1–4). Unticked = small barcode-only.
Invert image (tick this if it prints as a black block)
