Staples Thermal Paper Rolls, 2-1/4" x 75', 12 PackSuitable for use with most thermal calculators, cash registers and debit machines, Staples Thermal Paper Rolls are 100% BPA free to provide high quality, crisp, dark imaging. This printing media uses lint free premium stock to help reduces paper jams, which saves time and money. The hard plastic core keeps the paper roll uniform for smoother feeding to the printer, and is also economical as you can use the roll to the very end (unlike coreless rolls).
