Setting up receipt and label printers

A shop uses two kinds of paper: the receipt you hand to the customer and the label you stick on the goods (a tag in a jewellery shop). BuySale prints both, but one thing is worth knowing up front: the app does not connect to the printer directly. Receipts and labels go out through the browser print dialog — you pick the printer there yourself and set the scale to 100%. What the receipt shows is on the till page.

The receipt printer: 58 mm or 80 mm

There are two roll widths in the setting. A 58 mm roll gives a 48 mm printing area, an 80 mm roll gives 72 mm — with long product names and many lines, 80 mm reads better. Set whichever roll you actually have: otherwise the text is cut off at the edge or half the paper goes to waste.

The receipt carries the shop name, date, seller, items, total and payment type; a split payment shows each part with its own amount, and a phone shop also prints the IMEI and warranty date. After a sale the app asks whether to print. Later you can reprint any receipt from the sales history — if there was a return, the printed receipt shows the returned amount on its own line.

The setting belongs to the shop, not to the device

Profile has two separate rows: "Receipt printer" and "Label printer". The size you choose there is stored against the shop on the server, not on that one phone. So you set it once: the shop's other phones and computers, including a cashier who cannot open the settings at all, take the same size. One catch — a device picks up the new size the next time the app is opened. A cashier's app left open all day keeps printing the old size, so after changing it ask them to close and reopen the app.

These rows are visible to the owner and to a staff member given the "Settings" permission. A cashier without it never sees the setting — yet their receipts still come out in the size you chose.
