Choose Print Type First
Print Type decides the normal receipt path and what Auto Print uses after a sale is saved.
| Print Type | Best for | Operator check |
|---|---|---|
| Thermal | Till-roll printers such as 58mm or 80mm receipt printers. | Print one sample receipt on the actual counter device. |
| Regular / A4 | Full-page invoices or office printer output. | Check customer details, tax fields and page fit. |
| One-time Thermal button | A single customer needs a roll receipt even when the default is A4. | Use after sale save; it does not change the shop default. |
| One-time A4 button | A business customer needs a full invoice even when the default is thermal. | Use after sale save; it does not change the shop default. |
Set Size and Line Length
- Open Settings -> Core Settings -> Receipt Print.
- Select Print Type.
- Choose Print size for the physical paper or receipt roll.
- Set Print Maximum Character when product names wrap badly.
- Save settings.
- Create a test sale and inspect the tender preview.
- Print one sample and check width, line breaks, totals and readability.
Enable Auto Print
Auto Print should be the last step, not the first. The setting tells Posnic to print after sale save using the Print Type selected above.
- Confirm the printer is connected to the exact till computer.
- Use Hardware Manager or device setup to verify the local printer path.
- Print a receipt manually from a completed sale.
- Return to Receipt Print settings.
- Turn on Auto Print.
- Save settings.
- Create a small test sale and confirm it prints without cashier confusion.
Manual Fallback
- Keep Auto Print off during training if staff still need to review every sale first.
- Use Print receipt on the completed sale card when automatic print is off.
- Use Thermal or A4 buttons to override the default for one customer.
- Use Sales History reprint when a receipt is needed after the sale card is closed.
- If printing fails, do not recreate the sale; fix the printer and reprint the saved sale.
Daily Printer Check
| Before opening | What to verify | Why it matters |
|---|---|---|
| Printer online | The selected device prints a test receipt. | Auto Print cannot recover from an offline printer. |
| Paper type | Thermal/A4 matches the counter setup. | Wrong paper wastes time and creates unreadable receipts. |
| Product name length | Long item names wrap cleanly. | Crowded receipts confuse customers and staff. |
| Receipt total | Subtotal, discount, tax and total match the sale. | Receipt mistakes become accounting mistakes. |
| Fallback reprint | Sales History reprint works. | Staff need recovery when a print is missed. |
