We need a modern open-source barcode reader We need a modern open-source barcode reader. The best thing (zxing) is in maintenance mode, and the newer barcode scanners (scandit, mlkit) with niceties like neural scan, 90° scan, bortched barcode scan… are all closed source. |
Tbh, barcode thermal printers need an open source print driver other than Cups. I've been working on a project that both involves printing custom labels with Data-matrix qr codes and scanning them. Unless you pony up $400+ for a Zebra printer that has a "direct print" api that allows you to bypass common print drivers - using Cups is a huge pain. In many cases (at least on macs) it's nearly impossible to use a web passthrough to your local cups driver and commonly submitting a sequence of jobs incurs a 3-5 second delay between jobs. I now realize why there are entire companies built on top of proprietary print drivers and RPC channels to talk to printers. It's not that surprising though, since most of this problem space has been dominated and solved by Point of Sale companies. I'd definitely be open to any suggestions as to how I could better integrate printing to a rollo and scanning from a scanner or mobile device in a react app!
This would probably be a good Raspberry Pi project for someone thus inclined.
Edit: I found this project that says it can, so it's at least a 2-year old still-unanswered question of who will program it: https://www.pyimagesearch.com/2018/05/21/an-opencv-barcode-a...
