labelwriter

TypeScript-first Dymo LabelWriter driver suite for Node.js, browser WebUSB, and CLI.

• Repository: https://github.com/thermal-label/labelwriter
• Issues: https://github.com/thermal-label/labelwriter/issues

Note for LabelWriter 550 / 5XL users: These models enforce an NFC label lock — only genuine Dymo labels will print. This is a hardware restriction that cannot be bypassed. See the hardware guide for details.
