Print anywhere, from any phone.

Yes — that is exactly what it is for. Switch the printer on, open Bluetooth settings on your Android phone, select the NGX BTP device and pair once. After that it prints automatically from any app that supports ESC/POS — your billing app or a print utility — whenever the printer is within about 5 metres.

It comes down to paper width. The BTP120 (₹5,999) is a 2-inch pocket printer — the most portable, for a receipt you hand over on the doorstep. The BTP320 and the rugged BTP-3N (₹8,999) are 3-inch printers for wider bills, tickets and labels. All three pair with any Android phone and print over Bluetooth or USB.

Two worth knowing. Like every thermal printer, the print fades over months in heat or sunlight and is one colour only — fine for receipts and tickets, not for documents you must keep for years. And because it runs on battery and Bluetooth, it needs charging and works within roughly 5 metres of your phone. For field billing, delivery and van sales — print, hand over, move on — neither is a problem.

Yes — they support ESC/POS and ship with an Android SDK, so they work with most billing apps and custom software.

Standard thermal paper rolls — 2-inch (58 mm) for the BTP120, 3-inch (80 mm) for the BTP320 and BTP-3N. There is no ink or ribbon; the paper roll is the only consumable, so running costs stay low.

The BTP120 is a 2-inch pocket printer; the BTP320 and BTP-3N are 3-inch printers at around 307 grams — all easy to carry for a full day of field work on one charge.

No. A Bluetooth thermal printer — often shortened to a BT printer — pairs straight to your phone over Bluetooth, so it needs no Wi-Fi, no router and no SIM. Bluetooth and Wi-Fi are separate connections: the NGX BTP120, BTP320 and BTP-3N connect to any Android phone over Bluetooth and print on the move, and each also has a USB port as a wired backup.

A Bluetooth thermal printer is a portable receipt printer that pairs wirelessly with a phone or tablet and prints using heat on thermal paper, so there is no ink, no ribbon and no cable to the phone. NGX makes three: the 2-inch BTP120 at ₹5,999 and the 3-inch BTP320 and rugged BTP-3N at ₹8,999. Each runs on its own battery and prints bills, tickets and labels anywhere within about 5 metres of your phone.

Switch the printer on, open Bluetooth settings on your Android phone and select the NGX BTP device to pair. You pair once; after that it reconnects on its own and any app that supports ESC/POS, including your billing app, can print to it from up to about 5 metres away. Every model also has a USB 2.0 port if you would rather connect by cable.

NGX Bluetooth thermal printers start at ₹5,999 + GST for the 2-inch BTP120. The 3-inch BTP320 and the rugged BTP-3N are ₹8,999 + GST each. All three are one-time purchases with no monthly fee, bought direct from the manufacturer in Bengaluru rather than through a reseller.

Yes — the 3-inch BTP-3N prints 1D barcodes (Code 39, Code 128, ITF, Codabar, EAN and UPC) and 2D QR codes as well as bills and tickets. Label stock and receipt stock are both thermal paper, so the one printer covers both and there is no separate label model to buy. The BTP120 and BTP320 print bills and tickets over the same Bluetooth connection.
