58 mm vs 80 mm thermal printer for shop billing
Should a clothing shop buy a 58 mm or 80 mm thermal printer?
Buy an 80 mm (3 inch) printer if you print GST tax invoices or bills with many items: it fits about 48 characters per line and is easier to read. A 58 mm (2 inch) printer fits about 32 characters per line, is smaller and cheaper, and is fine for simple bills or a mobile counter. Both use thermal paper, so there is no ink cost.
