Why do some stores issue "oxidizing" receipts??

Urgh.... i bought something from Microcenter earlier this week, and it has a $10 mail in rebate... i took the receipt today to make a photocopy, so i have it for my records, and the receipt is already paritially "oxidized"... ie: it's turning black.

WTF is up with that?? By the time the receipt is mailed in, it will be completely oxidized.

 
It's heat-sensitive

Edit: It's not printed with ink, it's printed on thermal paper. Most stores with reasonably new POS systems do this
 
sometimes the paper is heat-sensitive and you put it near something... (ready?) hot. It happens when they throw your receipt in the bag when you drive thru fast food, etc. Paper doesnt oxidize, metal does
 
Yea, they aren't oxidizing. They are printed via a heat blaster that uses heat to print (the paper is heat sensitive). Expensive stuff.

As already described, it's paper for use in a thermal printer. If you really want to see it turn colors leave it on the dash of a sealed car in the middle of June.

even with no heat, they still fade. good way for stores to deny warranty i suppose, since you recepit won't be legible in a few months.
 
And to answer your question of why - no need for ink ribbons I'm guessing.

Edit: and quieter as mpitts mentioned
 
Well, if you find that you need a receipt to show information and has worn out, you can take a heat gun(or hair dryer) and blast the hell out of it. The thermal paper will then show a negative image of what was originally on the receipt. I used to do this with Trade-In credit slips that had lost their barcode when I worked for Gamestop.

I'm pretty sure that isn't why stores use them.

They are much quieter and don't require ribbons.
 
Thermal printers use no ribbon, have fewer moving parts, are fast, quiet, and reliable.

Yes, the paper is a bit more expensive than plain paper.

(Restaurants can use 'em for receipt printers but not for kitchen chit printers.)

Let me just repeat what you said, but in my own words now.

I love how people just paraphrase the same response that's already been posted 5 times.
 
They use these at some fast food places (like BK)... it's usually totally black from being stuck in the bag with the food by the time I get it.

Is there a problem with this paper being near food? After all, your receipt usually gets thrown right in the bag with your food at those fast food places.

My favorite is when people take the same response that has been posted 5 times, manipulate the words a bit, and then act like it's their own post.

No, the problem is that the clips for the chits are usually on the same surfaces that hold heat lamps.

I think that everyone in this thread is a NEF except the original poster who had a legitimate question.

And I also think that nobody cares what I, or just about anybody else in this thread, thinks.
