A printer for each document type
Create printer profiles for A4, A5, K80 and K58 receipts or barcode and label printers, then map each document type to one. Copies, paper size and orientation can be overridden per mapping.
xDev Browser Print
The right printer for every document.
A Chrome extension and a TypeScript SDK that let web apps for clinics, pharmacies and shops print prescriptions, invoices, receipts and labels on the printer set for each document type. No backend, no native app and no cloud print service.
In Chrome Web Store review
Free and open source under the MIT licence. No account. No tracking.
Features
Name the document. The extension picks the printer.
The web app sends a document type such as PRESCRIPTION or RECEIPT. An administrator decides once which printer handles it.
PDF and HTML through Chrome
PDF and HTML documents open Chrome’s print dialog, already set to the right paper size and orientation.
Receipt and label printers without a dialog
Printers that accept raw commands (ESC/POS, ZPL, TSPL) print directly over WebUSB or Web Serial, only on devices you granted on the Devices screen.
Only the websites you allow
Each web app is allowed by its exact address, with no wildcards, and Chrome asks for access to that one site. Permissions are per site: read the configuration, print, change mappings. You can also ask before every print.
Built to be safe
Site HTML is sanitised and rendered in a sandboxed frame. Each site has a rate limit and a size limit, and a repeated request with the same key does not print twice.
TypeScript SDK and React hook
The web app connects, prints a PDF, HTML or raw commands, and follows each job’s state with the @tdduydev/browser-print SDK or its useBrowserPrint hook.
Admin screens
Dashboard, printers, document mapping, devices, test print, print history, websites and settings, in English and Vietnamese.
Honest about Chrome’s limits
Chrome does not let extensions list or choose system printers, or report whether the user printed or cancelled. PDF and HTML always use the dialog unless an administrator starts Chrome with --kiosk-printing.
Privacy
Documents stay on the computer
The extension makes no network requests of its own. It has no server, no account, no analytics, no ads and no tracking. A document goes only to your printer.
Read the privacy policy- A document is kept only while its print job runs, then deleted.
- Print history keeps metadata only, never document content.
- No access to any website until you allow it, and then only that one.
Get started
An extension, an SDK and the source.
Chrome extension
In Chrome Web Store reviewManifest V3, for Google Chrome 118 or later on Windows 10 and 11, macOS and Linux. It has been submitted to the Chrome Web Store and is waiting for Google’s review; until then, developers can build it from source and load it unpacked.
SDK for web apps
npm install @tdduydev/browser-printTypeScript, ESM and CommonJS, with no backend dependency. The useBrowserPrint hook works with React 18 or later.
Open source
MIT licenceThe extension, the SDK, an example React app and the design documents are on GitHub at github.com/tdduydev/xdev-browser-print.
The extension is available in English and Vietnamese.
