[cups] Fwd: `ipptool` + `ippserver`: Differences between "ippsample"- and "cups"-GitHub repos?

[Michael Sweet]

Kurt,

The ippfind and ipptool programs will remain in CUPS and are kept in sync.

Similarly, lib cups in ippsample comes from CUPS.

The ippserver program in both projects is sample code. The version provided in the CUPS sources isn’t meant to be used as-is (some people use it for testing/prototyping) and I wrote it more as proof that a conforming IPP server could be written in a single source file.

The ippsample version is much more complex/complete and is being used to prototype things like IPP INFRA and the forthcoming IPP System Service specification. And that version may at some point in the future be used as the basis for a lighter weight print system for Linux, etc.

Feature-wise, ippsample’s ippserver adds support for multiple print queues/printers, transforms, 3D printing, and “cloud” printing. It will also be adding authentication, system service support (for remotely managing print queues, resources, etc.), release printing, and other bits as time permits. The CUPS version is in “maintenance” mode and will never be updated as a supported user application.
