Identify the selected code
POS Central UK lists code 3758B as 80 mm width by 80 mm diameter by 12.7 mm core,one box of 20 plain thermal rolls. The selected page declares 80 metres per roll. That gives 1,600 declared metres per carton by multiplication,not by measuring the physical contents.
Keep dimensions and length separate
The three dimensions are not three lengths of paper. Core size also needs a precise definition when compared with a machine’s separate internal and external spool requirements. The reviewed listing does not establish every core tolerance,paper thickness or exact certified original paper grade.
Separate price inclusion from performance
The selected quote shows£25 excluding tax and£30 including tax. Our default payable-price comparison uses the displayed£30 inclusive amount and does not add VAT a second time. A supplier statement about crisp printing or fewer changes is not our measured print-quality or operational result.
Ask about unlisted media fields
Before an exact-device order,ask about missing grade,tolerance and spool details using code 3758B. The broad supplier compatibility wording does not override the machine manual. No carton was physically inspected or run through a printer,and no live stock reservation or delivery deadline is implied by this observation.
Apply the field to a purchase
If a procurement sheet requires 80 mper roll,retain that declaration beside 3758B. A nominal 80 mmoutside diameter on another supplier’s box cannot be used as evidence that the same length requirement is met.
