Thermal receipt printers
Khata does not need a particular printer brand. On a phone it talks to Bluetooth thermal printers directly, which covers most counter printers sold in India and Nepal. On a computer it prints the way every other web page does.
Before you start
- A Bluetooth thermal printer, 58mm or 80mm, for phone printing.
- Bluetooth permission granted to the app.
- For the dashboard: any printer your computer can already print to.
Setting it up
Each step says who does it, so you are never looking for a screen that does not exist.
- 1
Pair the printer with the phone
YouPair it in the phone's own Bluetooth settings first, the same as a speaker or headphones. A printer that will not pair there will not pair in any app.
- 2
Select it in Khata
YouChoose the paired printer in the app's print settings and print a test receipt. Set the paper width to match the roll you actually use.
- 3
On the dashboard, just print
YouThe dashboard opens your computer's normal print dialog, so anything your computer prints to will work — thermal, laser or PDF.
What moves, and in which direction
- App → printer
- The receipt, over Bluetooth. Nothing goes through our servers to print.
How to know it worked
- Print a test receipt before the first busy hour, not during it.
- Check the width: text spilling off the right edge means the paper width is set wrong.
What this does not do
- No cloud printing and no network (LAN or Wi-Fi) printer support — Bluetooth on the phone, or your computer's own printer from the dashboard.
- No cash-drawer trigger and no customer-display support.
- Thermal receipts fade with heat and time. They are not a durable record; your Khata data is.
When it does not work
- The printer does not appear in the app.
- Pair it in the phone's Bluetooth settings first, and check the app has Bluetooth permission. On Android, nearby-device permission is separate from Bluetooth being on.
- Receipt prints cut off at the right.
- The paper width setting does not match the roll. 58mm and 80mm are not interchangeable.
- Prints blank paper.
- Thermal paper has a printable side. If a fingernail dragged across it leaves a grey line, that side faces the head.
