Have a nice day

Which of these would be a best-practice for thermal printer output?

A) Don’t use paper clips on thermal printer output

B) Don’t keep the output in large stacks

C) Don’t put the output near a heat source

D) Don’t store the output in a cardboard or paper folder

E) Always stamp your thermal printer output with a big smiley face

The answer: C) Don’t put the output near a heat source

Thermal printers operate by heating a portion of a special chemical paper to show the output. If the paper is left in a hot area, the rest of the printout will turn that color and obscure the original output. Leave one of your thermal-printed receipts on your car dashboard, and you’ll see what I mean.
