Crate ipp_printer_app 

Pure-Rust IPP Everywhere framework for building CUPS-driverless “printer applications” — the modern replacement for the PPD-driven filter+backend model.

The framework runs an axum HTTP listener that speaks IPP over POST on /ipp/print/<printer-name>. It’s device-agnostic: a consumer crate supplies a DeviceBackend (enumerate physical devices, poll their status) plus a RasterDriver (turn a PWG raster page into device bytes), and the framework handles the rest — job registry with monotonic ids, Get-Jobs/Get-Job-Attributes/Cancel-Job, background status polling, optional mDNS / DNS-SD advertising (enabled by the default mdns feature), JSON state persistence.

See examples/minimal_server.rs for the smallest end-to-end usage.

Modules

attributes

Build Get-Printer-Attributes / Validate-Job IPP responses.

device

DeviceBackend trait: enumerate physical devices, resolve driver names, poll live status.

flags

IPP printer-state-reasons bit flags (PWG 5101.1 keywords).

job

Per-server job registry: allocates job-ids, tracks state for Get-Jobs / Get-Job-Attributes / Cancel-Job.

mdns

mDNS / DNS-SD advertising for IPP printers (_ipp._tcp.local.).

printer

Per-printer configuration and runtime state.

raster

RasterDriver trait + page-header DTO for raster print jobs.

server

Axum HTTP server: IPP over POST /ipp/print/:name.

state

Persisted printer list (JSON).

status

Background printer-state-reasons poller.
