WebPrintingBlockedForUrls

Block WebPrinting API on these sites
Last updated March 31, 2026

Setting the policy lets you list the URL patterns that specify which sites are automatically denied access to local printers via the WebPrinting API. Valid patterns are limited to Isolated Web Apps. Leaving the policy unset means DefaultWebPrintingSetting applies for all sites, if it's set. If not, users' personal settings apply. URL patterns must not conflict with WebPrintingAllowedForUrls. Neither policy takes precedence if a URL matches with both. For detailed information on valid url patterns, please see https://chromeenterprise.google/policies/url-patterns. * is not an accepted value for this policy.

Example value:

{"0":"isolated-app://aerugqztij5biqquuk3mfwpsaibuegaqcitgfchwuosuofdjabzqaaic"}
