Cool! Side note, did you know a lot if these receipts contain PBA? In an experiment it was proved that people who handle many receipts, like Cashiers at tills, with PBA in them have much higher levels in their blood.

There's still plenty of places that specifically require a scanned copy of documents, instead of the original digital one. The printing and scanning process essentially makes it blurry and that's exactly what they want. I wonder if there's any tool that can achieve the same effect.
When I experience this, they want a “real” signature made by hand with pen ink, but scanned and sent. Although I keep a few signatures ready in Preview, these do not suffice. I need a tool that makes the signature look like it was created with a blue ink ballpoint.
I have scanned “real” signatures in blue and black with 3 different pens as transparent pngs for exactly this reason. Best 5 minutes in Photoshop I’ve ever spent.

Re: I built a receipt printer for GitHub issues
#174This is a fun idea, but I've read thermal paper is surprisingly nasty stuff. [Edit: unless it's advertised as "phenol-free".] It's not just paper. It contains plastics (BPA or BPS) that you absorb through your skin when handling it. I'd avoid working with receipts at my desk all day. (I'd also avoid being a grocery store cashier...) https://www.pca.state.mn.us/green-chemistry/bpa-thermal-pape...
BPA free thermal paper has been around for a while. A few years ago, I bought a box of it for a similar project (JIRA events -> Receipt printer)
BPA is hardly alone as a hormone disruptor in the world of plastics.

Pros: faster, quieter, better quality, don't need to know how to load ribbon when it runs out. Cons: fancy paper, fades over time, destroyed by even minor heat. We switched from dot matrix receipts to thermal a few years ago and there were several very vocal complaints about the relative impermanence of a thermal receipt.
Reading the thread for "minor hear" There was essentially no reasonable distance at which we could store the to-go pizzas from their accompanying thermal receipts where information the receipts contained would be recoverable.
Good point, I forgot about food. We don't sell anything hot, but a lot of our customers work out of trucks or vans and some complained that the receipts were unreadable after leaving them in their vehicles in the summer.

I bet code reviews with markers are fun though.
I've done code reviews on paper, although mostly when I want to understand something, not for review purposes.
I've printed long, MESSY, code, huge functions, to review and cleanup.
I loved working with engineers and using their plotter for that. Had a ton of space to actually write things out and draw connections.

english == Made in America; Quality. metric == Chinese; Piece of crap is the intention I think. Not a fair distinction imho, but to each their own.
I am buying these off eBay in the United States. English units might mean "culturally sensitive" which is a tracer for quality. A Zebra or NCR sold in the US will be marketed with English units, the same printer is probably marketed in the E.U. with metric units. The people selling the off brand printer might not know or could care less what units are used in the area it is being marketed in, which is a tracer for th…
English Units? How many barleycorn wide does it print? And how many wapentake (that's 20 knights fees) did you pay?
