Use the exact model instructions
Epson TM-T20III warns that after changing from80 to58mm and using the printer, it cannot be changed back to80mm. This is a model-specific instruction, not a statement about every receipt printer.
Avoid a generic conversion recipe
Star’s receipt and SK label manuals are separate, and different generations can have different details. This site links the correct reference rather than giving one set of guide or cutter instructions for all printers.
Update the reorder record
After an authorized configuration change, keep the actual configured width with the printer and paper SKU. Otherwise a future buyer may reorder for the original configuration by mistake.
Before you decide
- Read exact manual first
- Do not assume reversibility
- Update configured-format record
