Why Pubs and Bars Need Reliable Receipt Printing

Why the till roll is the quiet workhorse of a busy bar

Nobody opens a pub because they love receipt paper. Yet on a Friday night, the humble till roll is doing more work than almost anything else behind the bar. It records the round that was just poured, gives the customer proof of what they paid, and hands you a paper trail when a tab is disputed at 11pm. When a printer jams mid-service, staff start scribbling on the back of a beer mat, and by closing time the numbers no longer add up.

Reliable receipt printing is not about looking polished. It is about speed, accuracy and being able to close the till with confidence. Get the paper and the printer right, and the whole shift runs calmer.

Match the paper to the printer, every single time

Most pub EPOS tills use a thermal printer, which means the paper is heat-sensitive rather than inked. It is quiet, fast and needs no ribbon, but it will only do its job with the right stock.

• Width: standard tills take 80mm rolls, while handheld PDAs, card machines and smaller bar printers often take 57mm.
• Roll diameter: an 80mm x 80m roll is the common bar standard. If your printer housing is shallow, a fatter roll simply will not fit — or it will rub and drag.
• Core size: 12.7mm plastic cores suit most tills, but check whether your spindle needs a 25mm core. A mismatched core leads to wobble and misaligned printing.
• Grade: look for a smooth thermal grade around 55–70gsm. Very cheap paper has a rougher coating that wears the print head faster, and print heads cost far more than a box of rolls.
• BPA-free: increasingly expected, and worth specifying if staff handle receipts all shift.

Impact or dot-matrix printers still exist in older tills and kitchens, and they take plain or two-ply carbonless rolls. Never mix the two types — thermal paper in an impact printer is a waste, and plain paper in a thermal printer comes out blank.

Tabs, refunds and the paper trail that protects your margin

A printed receipt is evidence. When a customer says they were charged for two rounds instead of one, the duplicate copy settles it in seconds. When a member of staff voids the wrong item, the refund slip shows who did it, when, and for how much.

Open tabs benefit most. A printed tab slip with a table number or customer name means anyone on shift can pick it up and keep serving. It also means the bar is not relying on memory at the busiest point of the night.

At close, your Z report is only as good as the transactions behind it. Missing or illegible receipts create gaps, and gaps in the till usually mean stock unaccounted for — every pint, packet of crisps and short measure that never made it onto a slip. For pubs running food, the kitchen docket and the customer receipt should both come off clean paper, every time, so allergen notes and order details stay readable.

Keeping printers alive through a busy Friday

Most printer failures are preventable. A few habits make a real difference:

• Clean the thermal print head weekly with an isopropyl wipe, and always after changing a roll. Grease from fingers and dust from paper are the main causes of faded print.
• Let the head cool before loading a new roll. Thermal heads run hot on a busy night.
• Keep paper away from the cellar and any damp store. Thermal paper absorbs moisture, curls at the edges and then jams.
• Store rolls flat and sealed until use, away from direct sunlight and radiators.
• Do not over-tighten the roll on the spindle. It should turn freely with a light tug on the paper.
• Watch for a fading print head or a squealing motor. Both fail suddenly at the worst moment, so replace rather than repair when a printer starts misbehaving during peak trade.

How much paper should you actually hold?

Do the arithmetic on your own trade. A receipt is roughly 15–20cm long, and a standard 80mm x 80m roll gives you around 80 metres — somewhere near 400 to 450 receipts. If your pub pushes 500 transactions on a Saturday, that is two rolls minimum for one night, plus waste from reprints and test prints.

A sensible rule is to hold six to eight weeks of stock per printer, with a spare box kept somewhere dry and easy to reach. Ordering a single box in a panic costs more in delivery and lost service than keeping a modest buffer on the shelf. Buy from a supplier who stocks both 80mm and 57mm as standard, so you are not waiting a week for a size you ran out of on Sunday.

Small details that keep service moving

Label the printers behind the bar, so a new starter knows which one serves the kitchen and which one serves the card machine. Keep a spare roll within arm's reach of each till — a two-minute dash to the stockroom during a rush feels like twenty. Train everyone on how to change a roll properly, including which way the paper feeds, because loading it backwards is the single most common and most avoidable fault.

Get these basics right and the till roll stops being a nuisance. It becomes what it should be: a fast, reliable record of a good night's trade, and one less thing for your team to worry about when the bar is three deep.
