Bluetooth printer + Android phone — bill printing without a laptop.
Pair the printer in the phone's own Bluetooth settings first. Then open EasyKOT → Device tab → Printers → Add printer, choose Bluetooth printer (already paired), pick it from the list, set 80mm or 58mm, and Save printer. Press Test print. If a slip comes out, that phone can print KOTs and bills — this is how you run the whole restaurant from one Android phone.

What you need.
- An Android phone. Bluetooth printing is Android only — Apple allows only its certified printer models, which the common ₹2,000 printers are not. iPhones run the captain app perfectly well and print to Wi-Fi printers; for a Bluetooth printer, the printing phone is an Android.
- A Bluetooth thermal printer, charged and switched on. 58 mm or 80 mm, speaking ESC/POS. Keep the box: the printer ships with a pairing PIN, usually 0000 or 1234.
- A manager PIN. Turning a phone into the store's printer asks for one — printing is a decision about the whole shop, not a personal setting. Turning it off again is a single tap, on purpose.
- Battery, honestly. A phone that is printing all evening is a phone on a charger. Keep a cable at the counter.
Reading this on a laptop? You can try the register in your browser — it runs the real till, though printing is the one thing a browser cannot do. On a phone, the better door is the Android phone register.
Pair it, add it, test print.
Pair the printer in the phone's own Bluetooth settings
Switch the printer on, then pair it from Android's Settings → Connected devices → Bluetooth, exactly as you would a pair of earphones. EasyKOT deliberately does not hunt for unpaired printers — it only offers devices the phone has already bonded with, so pairing happens once, in the place Android already handles it.
Open the Device tab in EasyKOT and scroll to Printers
The app's bottom bar has three tabs — Running, Free and Device. Printers is a section on the Device tab. With nothing added it reads "No printer yet. KOTs and bills can print straight from this phone."
Tap Add printer, then Bluetooth printer (already paired)
The phone lists every Bluetooth device it is paired with, by name and address. Tap your printer. If the list comes back empty the app tells you plainly: pair the printer in the phone's Bluetooth settings first, then come back.
Device tab → Printers → Add printer, on an Android phone. Bluetooth leads because it is the one that needs no router.
Set the paper size and what this printer prints
Paper is 80mm or 58mm — match the roll you buy. Prints is the role: Everything, KOTs, or Bills. On a one-phone shop leave it on Everything. Tap Save printer.
Prints is the role and Paper is the roll. On a one-phone shop, leave Prints on Everything.
Test print, then turn phone printing on
Tap Test print; the app answers "Sent — check the printer." Once a slip comes out, tap Print from this phone (manager) and enter a manager PIN. The status line then reads "This phone is the printer — KOTs and bills print here."
“Sent — check the printer.” The app is careful never to claim the paper came out — only that the bytes left the phone.
After the manager PIN: “This phone is the printer.” Turning it back off is the single tap right below it.
The notification is meant to stay. While the phone is the printer, Android shows an ongoing notification reading EasyKOT is the printer / KOTs and bills print from this phone. That is what keeps the print queue alive while the phone is in an apron pocket. Swiping it away is not the way to stop printing — Stop printing from this phone on the Device tab is.

"Bluetooth permission not granted."
On Android 12 and newer, an app may only talk to a paired Bluetooth device if you have given it the Nearby devices permission. The first time you tap Bluetooth printer (already paired), EasyKOT asks for it — choose Allow and the paired-printer list opens. If you dismiss the ask, tapping again asks again; the printer itself is fine either way.
Said "Don't allow" one time too many? Android stops showing the ask, and only its own settings can turn the permission on: Settings → Apps → EasyKOT → Permissions → Nearby devices → Allow. Reopen the Device tab and tap Add printer again; your paired printer will be in the list — EasyKOT tells you this exact path on the failed screen too.
The real screen, on a real Android phone. It spells out the Settings path rather than leaving you at a dead end — and Try again works the moment you come back.
- Bluetooth is turned off means exactly that — pull down the shade and switch it on.
- No paired Bluetooth printers means the phone has not bonded with it yet. Go back to Android's Bluetooth settings and pair it there first; EasyKOT never scans for unpaired devices.
- Could not connect to printer with an address in it means the pairing exists but the printer is not answering — is it on, in range, and not already connected to somebody else's phone?
Bluetooth ya Wi-Fi printer — kaunsa lein?
Bluetooth, if it is one phone at one counter
- No router in the path. The phone talks to the printer directly, so a dead broadband line or a rebooting router changes nothing.
- Cheapest to start. A battery 58 mm Bluetooth printer is the standard kit for a takeaway counter or a stall.
- One phone at a time. That is the real limit, and it is a hardware one, not ours.
Wi-Fi, if more than one device prints
- Several phones, or a phone and a laptop can all send to the same Wi-Fi printer by IP.
- It can sit in the kitchen while the phone walks the floor — Bluetooth range keeps a printer beside you.
- Reachability is knowable. A network printer answers a probe, so the app can tell you it has gone away. A Bluetooth printer's honest check is always the test print.
Either way, the phone-side flow is the same — Add printer → Wi-Fi / LAN printer (enter IP) instead of the Bluetooth option, then the printer IP and port 9100. For the counter laptop version, see connecting a Wi-Fi or USB printer to the register.
The Wi-Fi path — two fields, and 9100 is already filled in because that is the port essentially every ESC/POS printer listens on.
The printer stopped appearing in the list.
- Check the pairing survived. Some cheap printers drop the bond when the battery fully dies. Android's Bluetooth settings will show it as unpaired — pair it again and it reappears in EasyKOT.
- Another phone may be holding it. Bluetooth printers take one connection; if last night's phone is still connected in the back office, this one cannot get in.
- The permission may have been reset. Android revokes permissions for apps you have not opened in a while. Re-grant Nearby devices and it comes straight back.
Nothing is lost while you sort it out. Every bill and every KOT is written to the phone before it is queued to print, and the queue keeps retrying on its own. If a ticket died mid-print the phone asks you plainly — "One ticket may or may not have printed — check the printer and answer" — with It printed and Print again (marked duplicate). Nobody has to guess.
Still nothing on paper? Work through the nine printer checks, in order.
Bluetooth printer se KOT bhi print hoga?
Haan. The Prints setting on each printer decides: Everything, KOTs, or Bills. One printer on Everything gives you a kitchen ticket when you fire a round and a GST bill when you settle — off the same roll, from the same phone.
- A second round prints only the new items, headed with the round number, so the kitchen never cooks a dish twice.
- Two printers, two jobs. Add a second one and set it to KOTs while the counter one takes Bills — the same split a laptop register does with a kitchen KOT printer.
- Paper only, in a phone-only shop. The phone prints kitchen tickets; it does not drive a kitchen display screen. A screen in the kitchen needs a laptop register hosting it.
- Waiters can still carry phones. Other phones running the captain app send their rounds to the printing phone. There is no per-waiter or per-phone charge.
The same Bluetooth printer, on the desktop register.
A laptop reaches a paired Bluetooth printer as a serial port, so on the desktop register it lives under Serial / Bluetooth — same idea, different screen. Pair it in the computer's own Bluetooth settings first, exactly as on the phone.
Desktop register · Settings → Printers & KDS → Add manually, on Serial / Bluetooth.
Detect printers on the laptop finds paired Bluetooth devices too, but it is honest about what it knows: a bonded printer is listed under Other devices on this computer with the reason "Paired Bluetooth device — try a test print", and a soundbar sitting next to it is demoted with "Looks like another accessory, not a printer". Nothing is hidden from you; it is just ranked.
Desktop register · Settings → Printers & KDS → Detect printers → Other devices on this computer.
Always finish with a test print. A network printer can be probed, so the register genuinely knows when it goes away. A Bluetooth or USB printer shows as configured with its status unknown — the slip in your hand is the only real proof, on the phone and on the laptop alike.
