Hardware and the kitchen
Printers
Menu: Printers · Who: owner, branch manager
Printers belong to a branch. One shop can have three: the counter receipt printer, a kitchen printer, and an A4 printer for invoices.
Where each type actually prints
A browser cannot open a network socket or a Bluetooth port. That is why the transport matters:
| How it is reached | Runs on | Available |
|---|---|---|
| This device (browser print) | The web POS itself — the browser's print dialog | now |
| Sunmi cloud printer | Our server sends the job to Sunmi's cloud; nothing is installed in your shop | now, once Sunmi credentials are added |
| Network printer (LAN) | The Sellify Android app on that terminal | with the Android app |
| Bluetooth printer | The Android app | with the Android app |
| Sunmi built-in printer | The Android app on a Sunmi terminal | with the Android app |
If you set up a printer the web POS cannot drive, it will not pretend: it hands you the receipt and says the job is waiting for the app.
Adding a printer
| Field | Notes |
|---|---|
| Name | What the cashier will see on the Print button: "Counter", "Kitchen" |
| Branch | Which shop it sits in |
| Prints | Customer receipt, Kitchen ticket, or A4 invoice |
| Paper | 3 inch (80mm), 2 inch (58mm), or A4 |
| How it is reached | The transport from the table above |
| IP address / Port | Network printers. Port is 9100 unless yours differs |
| MAC address | Bluetooth printers |
| Serial number | Sunmi printers — the SN printed on the device |
| Cloud key | Sunmi cloud only. Stored encrypted and never shown again |
| Copies | 1 for most shops, 2 where a copy is filed |
| Cut the paper | Thermal only |
| Open the cash drawer | Thermal only — kicks the drawer when the receipt prints |
| Default for this job | The one this branch reaches for. One default per job |
| In use | Untick to park a printer without deleting it |
Test print
Every row has Test print. It prints a real receipt marked *** TEST PRINT ***, so
nobody files it as a sale. Do this before the shop opens, not during a rush — it is the
fastest way to know a setting is right.
Paper sizes
| Characters across | What it is | |
|---|---|---|
| 3 inch (80mm) | 48 | The normal counter receipt |
| 2 inch (58mm) | 32 | The same receipt, tighter |
| A4 | — | A different document: letterhead, item table with tax per line, totals, signature lines |
Use A4 for a customer who needs a proper invoice; use 80mm or 58mm at the counter.
Rules the system enforces
- A network printer needs an IP, a Bluetooth one a MAC, a Sunmi one a serial number — a printer nobody could reach is refused when you save it.
- A thermal printer cannot be set to A4, and an A4 printer cannot be a kitchen ticket.
- The cloud key never comes back to the browser once saved.
What the receipt says
Where it prints is this page. What it prints — logo, address, NTN, tax breakdown, footer — is Settings → Receipt & Printing.
