Built a hardware device that sits between any computer and any printer and reads what is getting printed.

Primary use-case is to read receipt data from legacy POS systems without having to write software integrations.

Figuring out how to commercialise. Reach out if you have ideas!

fond memories. we did tv guides for a local cable system for a bit in the early 90s. they had a customer db, but no "export" beyond sending print jobs to their bigarse line printer.

but it was a parallel port and i had use of a luggable with a bidirectional parallel port so i'd haul that in once a month, hook it up, and have them run a "hello customer" fake billing run, which was hoovered up and stripped down to the address list we needed to mail to that month.

Have a look at the Internet Printing Protocol. I built a NodeJS app that pretended to be a printer and could receive real time transactional data from a legacy POS/software. No drivers required… supports HTTP auth… all OS’s have great support for it.
