Printing & Thermal Receipts

Print a full A4 tax invoice, or a thermal receipt sized for the 58mm and 80mm rolls counter printers use.

Not every customer wants a PDF. A shop counter needs paper in hand, and the paper it needs is a narrow till roll, not an A4 sheet. InvoiceKaro prints both.

Two formats

Note
Both are the same invoice, so both carry the same number and totals. The receipt is a compact rendering, not a second document.

Printing an invoice

  1. 1Find the invoice — In the Invoices tab, tap ⋯ More on its card. Drafts print too — you don't have to issue an invoice to put it on paper.
  2. 2Choose the formatPrint gives the full A4 tax invoice; Print receipt (roll) gives the thermal receipt.
  3. 3Pick your roll width — For a receipt, choose 58mm or 80mm to match the paper in your printer.

On a quick bill, Save & print skips all of this and sends the receipt straight out.

Receipt width

Thermal rolls come in two common sizes. 80mm is the usual desktop till printer; 58mm is the narrow roll used by handheld and Bluetooth printers. Picking the wrong one gives you cut-off text or a wastefully narrow column, so check the roll before your first print.

Tip
Thermal paper is continuous, so a receipt has no fixed page length — it's as long as the sale needs. A twenty-item bill simply prints a longer slip.

Connecting a printer

InvoiceKaro prints through your device's own printing, so anything your phone or computer can already print to will work — a USB or network till printer, a Bluetooth handheld, or Save as PDF.

  • Android — install your printer's plugin or Mopria, then it appears in the print dialog.
  • Windows / macOS — any installed printer works, including shared network printers.
  • Bluetooth till printers — pair the printer in your device settings first; it then shows up like any other.
Check the width before a busy day
Run one test receipt on the actual roll you use. A width mismatch is obvious on paper and invisible on screen.
