DYMO NPAPI Addin
DYMO NPAPI Addin is an internet plug-in that integrates DYMO label-printing functionality into web browsers. It enables web applications and online label-printing services to access DYMO label printers directly from the browser, allowing users to print labels without standalone software. This plug-in was commonly used with legacy web-based label-design platforms before modern browser APIs made NPAPI plug-ins obsolete.
AI Recommendation
1 suggestionDYMO NPAPI Addin is an internet plug-in for macOS browsers, and it is no longer maintained. Apple has deprecated and effectively removed support for NPAPI (Netscape Plug-in Architecture) from Safari and other modern browsers — NPAPI plug-ins have not worked in Safari since version 12 (released in 2018) and modern versions of Chrome and Firefox have also dropped NPAPI support entirely. Even if an Intel-only build were still available, it would not function in any modern browser on any Mac, regardless of architecture. The DYMO company has since transitioned to browser-based JavaScript APIs and cloud printing services, so any modern DYMO printing workflow uses the vendor's web portal or native DYMO software (like DYMO Label) rather than this legacy plug-in. You can safely remove this plug-in from your system — it serves no purpose on current macOS versions and will not work once Rosetta 2 is removed in macOS 28 (September 2028). If you still need to print DYMO labels, visit dymo.com and download the latest native DYMO Label desktop application or use DYMO's web-based label service.
