Before RollFix
The roll catches on the printer base
Watch how the unsupported roll sits low and resists turning freely.
Royal Mail label roll change — printers affected
Fix the 44mm label-roll problem in your thermal printer.
Royal Mail changed their rolls. We fixed your printer.
Royal Mail currently supplies 6×4 thermal label rolls with a 44mm internal core. In some compatible thermal printers, the larger core allows the roll to sit lower and drag against the printer base, causing poor or interrupted label feeding.

44mm → 25mm core fix
£6.95a pair · delivered
A small part. A costly irritation removed.
Why is your printer struggling to feed labels?
The larger core can let the roll sit lower on the spindle, so its outer edge rubs against the printer base. RollFix reduces the core opening and lifts the roll into a better feeding position.

After RollFix
The roll is lifted into a better position
