THE REFERENCE SHELF
Printer & fit
Start with the printer, not the roll’s width
Record the exact printer model and media requirements before comparing an offer. Width alone cannot certify a roll for your machine.
Narrow and wide rolls solve different output requirements
A lower price for a narrow roll is not an automatic substitute for a wider receipt format. Check the exact configured printer and layout.
TSP143IV is not TSP143IV SK: keep the model suffix
A nearly identical model name can describe a different media job. Preserve suffixes and the intended printer type in a specification request.
Check the manual before changing a printer’s paper width
A paper-width change can require hardware and software steps, and some models impose limits after use. Do not treat a narrow roll as a reversible plug-in substitution.
