*Specification*
https://wicg.github.io/web-printing
*Summary*
Enables deeper integration with printer-related functionality in
Isolated Web Apps. This API is targeted at Isolated Web Apps only
and it's following the
https://www.chromium.org/blink/launching-features/isolated-web-apps/
process. This API provides a set of JavaScript methods that allow
developers to query local printers, submit print jobs to the most
appropriate printers, and manage print job options and status. To
represent these concepts, it relies on the attribute names and
semantics from the Internet Printing Protocol (IPP) specifications.
*Blink component*
Blink
<https://issues.chromium.org/issues?q=customfield1222907:%22Blink%22>
Perhaps we should create a component for all IWA APIs or something? We
regularly triage <https://www.chromium.org/blink/blink-triaging/> bugs
out of the top-level Blink component so it's not a permanent home for
any bugs.
*Web Feature ID*
/No information provided/
*Motivation*
The Web Printing API strives to improve the general printing
experience with a primary focus on remote/virtual desktop systems
by providing a seamless way for remote clients to interact with
printers directly in Isolated Web Apps. The proposed API methods
unlock proper printer forwarding by allowing the remote client to
access essential information about printers on the near side. This
eliminates the need for tedious manual configuration, such as
setting up virtual printers, and excessive user interactions such
as having to click through print job settings twice (once on the
remote side & once locally). It also enables remote document
rendering to be tailored to the capabilities of the local printer.

*Risks*
*Interoperability and Compatibility*
Other browser may choose to implement this API.
/Gecko/: No signal
/WebKit/: No signal
/Web developers/:
Positive
(https://github.com/WICG/proposals/issues/120#issuecomment-1752979770) Positive
feedback from Citrix.
/Other signals/:
*WebView application risks*
Does this intent deprecate or change behavior of existing APIs,
such that it has potentially high risk for Android WebView-based
applications?
/No information provided/
*Debuggability*
/No information provided/
*Will this feature be supported on all six Blink platforms
(Windows, Mac, Linux, ChromeOS, Android, and Android WebView)?*
No
*Is this feature fully tested by web-platform-tests
<https://chromium.googlesource.com/chromium/src/+/main/docs/testing/web_platform_tests.md>?*
No
Web Platform Tests are planned for the cross-platform launch.
Creating Web Platform Tests will be complicated because this API
connects to physical devices and this would require extensions to
BiDi driver API.

*Anticipated spec changes*
Open questions about a feature may be a source of future web
compat or interop issues. Please list open issues (e.g. links to
known github issues in the project for the feature specification)
whose resolution may introduce web compat/interop risk (e.g.,
changing to naming or structure of the API in a
non-backward-compatible way).
