- Will it print correctly on my thermal printer?
- The PDF is generated at the true paper width — 58 mm or 80 mm — with the height growing to fit the content, so the driver has nothing to scale. Print at 100% with no page scaling.
- Does the receipt number increase by itself?
- Yes. The next number is kept on this device and steps forward each time you generate a receipt, so a busy counter does not have to track it. Clearing your browser data resets it.
- Is my shop's data stored anywhere?
- Only in this browser, on this device, so the next receipt does not need retyping. Nothing is sent to a server — there is no account and no database behind this tool.
- Is this a GST tax invoice?
- No. This produces a plain counter receipt for a service rendered. A GST tax invoice has legally required fields — GSTIN, HSN or SAC code, place of supply, tax split — and should be issued from proper billing software.
- Can I add my shop logo?
- Yes. Upload it once and it is kept on this device for later receipts. A simple high-contrast logo prints best — thermal printers have no greyscale worth relying on.
