Receipt paper sizes: getting the order right
Receipt paper is ordered by three measurements, not one, and ordering by width alone is the single most common supply mistake in a small store. A roll that is the right width and the wrong diameter will not fit the cradle; the right diameter on the wrong core will not turn.
Getting the specification written down once removes the problem permanently.
What are the three measurements?
Width, which must match the printer's paper path. Outside diameter, which must fit inside the roll cradle with the cover closed. And core diameter, the hole in the middle, which must fit the spindle if the printer has one.
Length follows from diameter and paper thickness rather than being specified separately, which is why two rolls of the same stated length can be different sizes.
How do you measure an existing roll?
Width across the roll face with a ruler. Diameter across the outside of a full roll. Core diameter across the hole. Write all three down with the printer model beside them.
Do it for every printer in the store, because they are frequently not the same — a counter printer, a kitchen printer and a portable unit can take three different rolls.
What about thermal versus bond?
A different question and an equally common error. Thermal paper is coated and prints by heat; bond paper needs an impact mechanism and a ribbon. Putting the wrong one in produces a blank receipt and a service call.
The coin test settles it: scratch the roll with a coin edge. A dark streak means thermal. No streak means bond, and it belongs in an impact printer.
Does paper grade matter?
Yes, in two ways. Coating sensitivity varies between grades, which can mean adjusting the printer's print density when you change supplier. And image stability varies, which matters for anything kept as a record.
If print quality changes after a new order, check the density setting before blaming the paper or the printer.
What about BPA-free and other chemistry?
BPA-free tells you one specific chemical is absent. It does not tell you what replaced it, and several alternative developers are in use. If that matters to you or your customers, ask the supplier what the coating uses rather than accepting the label as a complete answer.
Handling guidance is the same regardless: keep rolls cool, dark and dry, and away from solvents.
How much should you hold?
Your lead time plus a buffer, stored properly. Thermal paper degrades with heat and light, so a year's supply bought on a case price and stored near a warm wall is not a saving. The paper roll sizes are worth matching to your real burn rate.
What should the written specification look like?
One line per printer: location, model, paper type, width, outside diameter, core diameter. Taped inside the printer cover and kept with the ordering list.
That single card makes every future order correct regardless of who places it, which is the actual problem being solved.
Frequently asked questions
Why does my new roll not fit?
Almost always diameter or core, since width is the measurement people check. A roll that is fractionally too large will not let the cover close.
Can I use a narrower roll in a wider printer?
Mechanically sometimes, and the print will be misaligned and the paper may skew. It is a stopgap rather than a solution.
What length roll should I buy?
Whatever fits the diameter your printer accepts. Longer rolls of the same diameter mean thinner paper, which can affect print quality and tear behaviour.
How do I stop running out?
A reorder point based on rolls per week, and a working supply at the counter rather than only in the back. Both are simple and both are usually missing.
Does the printer need adjusting for a new paper brand?
Sometimes, via the print density setting. Check it when changing supplier rather than concluding the new paper is poor.
Can rolls be stored in the cold?
Cool and dry is right; cold enough to cause condensation is not. A roll brought from a cold store into a warm counter can be affected by moisture.
What about two-ply rolls?
Only for impact printers specified for multi-part paper. They will jam a printer that is not.
What is the first improvement?
Write the specification card for every printer today. It takes fifteen minutes and it ends the wrong-size order permanently.
### What about printers you have replaced?
Remove their paper from the ordering list at the same time the equipment goes. Orphaned consumables are the most common thing an annual supply audit turns up, and they were all created the day a device was replaced and the list was not updated.
While you are there, use up or return any remaining stock rather than storing it indefinitely.
Does roll length affect print quality?
Indirectly. Longer rolls of the same diameter are thinner paper, which can tear more easily and feed differently. If a new order of the same stated size behaves differently in the printer, check the thickness as well as the coating.
How do I compare two paper suppliers fairly?
On delivered cost per roll for your exact specification, and on print quality from a sample in your own printer. A lower price on a thinner roll of the same stated length is not the same product. Trade guidance for convenience retailers is collected by NACS.
