XJDF, XJMF and PrintTalk: contracts and delivery evidence
Standards, adapter reports and the difference between a valid document and verified device delivery.
NowToPrint keeps job data in a structure based on XJDF 2.2, XJMF 2.2 and PrintTalk 2.2. This is not a conformance claim. XJDF 2.2 describes print-job intent and resources, XJMF carries operational messages, and PrintTalk 2.2 describes commercial exchanges. Legacy JDF/JMF belongs at the external adapter boundary. A matching schema is not evidence that every field is supported by a device, that a job was printed or that a commercial action is approved.
Package and certification scope
The repository package @nowtoprint/xjdf is a private 1.0.0-beta.2 workspace
package. Its presence is not a public stable SDK or a promise that every provider
is available. The conformance reporter starts as self-assessed / draft.
A generated report or fixture does not establish independent CIP4 certification,
a completed interop event or measured production delivery.
Web DFE submission
The Web route POST /api/production/jobs/submit-dfe has its own organization and
authorization boundary. It is separate from a Desktop local API or Tauri command.
The current submitter uses the device-connectors factory; the supported factory
cases are Fiery, PRISMAsync and Konica Minolta. Configured type, host, protocol,
credentials, exact device capability and the installed release still need verification.
A supported factory case does not certify all models of that brand.
The route requires an idempotency key and reserves the organization-scoped submission. A repeated reservation can return 409; that does not return a verified receipt for an earlier print. After a timeout, preserve the operation identity and inspect the available result through the responsible team. Do not invent a new key to force another device submission.
Read adapter results before acting
A conversion can report unsupported fields, warnings and a need for manual review. Preserve those reports with the relevant job/order observation; do not silently treat an adapter bridge as native support. A device job ID, a queue position, an adapter success response and physical completion are different observations. An overall success field alone does not prove the final effect.
Fiery configuration defaults to port 443 and TLS in this Web submitter. That is not a claim that every vendor or protocol has the same transport policy. Use the exact admitted trust and device profile; a documentation example is not permission to bypass certificate checks.
Desktop connector boundary
Production Desktop uses separate service/connector admission, binding, maturity and field-evidence checks. Historical Tauri DFE or plugin compatibility code is not automatically registered in the production binary. A plugin manifest, content hash or registry state is not evidence of an isolated executable sandbox.
These notes describe source contracts. They do not authorize a customer pilot, public SDK publication or device delivery, and this review ran no live DFE test.
