The whole restaurant — one Android phone and one thermal printer.

The phone IS the register. Every bit of it.

• Order at the table, print in the kitchen. Menu with veg/non-veg marks, Half/Full portions, notes like "less spicy" — fire, and the KOT prints. Round two prints only the new items.
• Bluetooth or Wi-Fi thermal printer. Pair once in phone settings or type the printer's IP, test print, done — 58 mm or 80 mm. A failed print waits in the queue and retries; the sale is never lost.
• GST bills from the phone. Tax invoice per CGST Rule 46 — invoice series, CGST/SGST split, round-off. Set the phone up as a Register device (step 2) and the series is minted for it — the same continuous series the desktop register uses.
• Cash box on the phone. Opening float, paid-outs with a reason, count at close — expected cash and variance calculated for you, UPI shown separately.
• Works offline. Billing and printing run on the phone's own database — the net can come and go, the counter doesn't stop.

Android phones print to Bluetooth and Wi-Fi printers. iPhones print to Wi-Fi printers while the app is open — for Bluetooth printers, an Android phone or the desktop register does the printing.

A fired line can go down, never up. Table took three waters and sent one back? Drop the qty to 2 and the bill follows — no manager, no argument. It cannot go up, because the kitchen only cooks what a KOT named; a + opens a new line that rides the next fire. And it cannot reach zero — taking cooked food off a bill is a Void (manager) with a reason, which is exactly the moment an owner wants a record.

That is why the buttons change the instant you fire: Remove becomes Void (manager), and a grey rail marks every line the kitchen has already been told about.

The same table one second after Fire — the kitchen has it, so the line is now the kitchen's business too.

• Turn this phone into the printer — once. It asks for a manager PIN, because whether the shop's tickets come out of this phone is a decision about the whole shop, not a personal setting. After that the status line reads “This phone is the printer — KOTs and bills print here.” and Android keeps an ongoing notification alive so the queue drains even in an apron pocket.
• Turning it off is one tap. Stop printing from this phone — deliberately not buried, so a phone going home for the night can hand printing back in a second.
• The cash box lives on the same screen. Put the float in at open, record a paid-out with a reason when you buy vegetables, and at close the phone tells you what should be in the box — UPI counted separately, so a day that looks short usually just went to UPI.
• Reprint last bill is right there, for the customer who asks after the roll has moved on.

• No kitchen screen. A phone-only kitchen is paper-only. The kitchen display needs a register on the counter to host it.
• No cash drawer kick. A drawer opens off a printer port the desktop register drives. On a phone the cash box is a box — counted, not kicked.
• Bluetooth printers are Android-only. An iPhone can run the app and print to a Wi-Fi printer while the app is open, but Apple allows Bluetooth printing only to its own certified models — so budget Bluetooth printers need an Android phone.

• One Bluetooth printer, one phone at a time. That is the hardware's limit, not ours. If two people must print, put the printer on Wi-Fi and add it by IP on both.
• The printing phone is a phone on a charger. An evening of printing eats battery. Keep a cable at the counter.
• Reports live in the dashboard, not the phone. Day sales, what sold, food cost and profit against targets open in a browser — on that same phone, or any laptop.

The Device tab always says which way orders are travelling — and which store this phone belongs to.

Add printer → the two ways a phone can reach a thermal printer.

• Bluetooth — pair it once in the phone's own Bluetooth settings, exactly like earphones. EasyKOT never scans for unpaired printers, so pairing happens in the place Android already handles it.
• Wi-Fi / LAN — type the printer's IP and port 9100. This is the one to pick if the printer sits in the kitchen while the phone walks the floor, or if a second device needs to print too.
• 58 mm or 80 mm, ESC/POS — the standard nearly every receipt printer sold in India speaks. We publish no certified-model list on purpose: a ten-second test print answers it for your printer better than a list ever could.
