Receipts

What the receipt carries, how it prints on an 80 mm roll, and how to print one again later.

Every completed sale has a receipt. It is shown on screen the moment the sale completes and can be printed then or at any time afterwards.

What is on it

  • The shop's name, its licence number and its address and phone.
  • The sale number, the date and time, and who made the sale.
  • Every line: the product, the quantity, the unit price, the line total and the batch the stock came from. A line split across two batches shows both.
  • The subtotal, any discount, the total, the payment method, cash tendered and change.
  • If the sale was made without a valid licence on record, the receipt says so.

The batch on the receipt is what lets a pack be traced back to its delivery if a recall or a complaint ever comes in.

Printing on an 80 mm roll

The receipt is laid out for a thermal roll 80 mm wide, the ordinary till printer. It prints through the browser, so any printer the PC can see will do.

Set the printer up once

Install the printer's driver and make it the browser's default printer. In the browser's print dialogue set the paper to the printer's roll size (often called 80 mm × receipt or Roll Paper 80 × 297 mm), margins to none, and untick headers and footers.

Tick "remember settings"

Chrome and Edge keep the last print settings for the site, so after the first receipt the dialogue opens ready.

Print

Print on the receipt opens the dialogue; Enter confirms. On a phone, printing goes through the phone's own print service to a printer on the same Wi-Fi.

A cheap USB thermal printer with a cutter and an 80 mm roll is enough. Avoid printers that only speak a proprietary app; the receipt is a web page and needs a printer the operating system can drive.

Printing a receipt again

Open Sell → Sales by day, pick the day, and click the sale. The receipt opens with Print. Voided sales show their status on the receipt, so a reprint of a voided sale cannot be passed off as a live one.

Printing on plain paper

Nothing stops the same receipt printing on an A4 sheet from an office printer; it simply sits in a narrow column. Useful for a copy to staple to a supplier's return or a customer's complaint.
