GET /jobs/{jobId}

Returns the current state of a print job. The state is queried live from CUPS on each request.

Use this endpoint to poll for completion after submitting a job with wait: false via POST /print/{target}.

Note

Jobs are kept in memory for 1 hour after submission — poll promptly. After that, this endpoint returns 404 for the job ID.

Polling Example

// Submit a non-waiting print job
const printRes = await fetch('https://pbx-ABCD.pbxz.io/api/v1/print/tag_LABELS', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json', 'X-API-Key': 'ULA9WHXMFCHF' },

    contentType: 'raw_base64',
    wait: false
  })
});
const { result } = await printRes.json();
const jobId = result.content.jobId;

// Poll until complete
let state = 'queued';
while (state === 'queued' || state === 'printing') {
  await new Promise(r => setTimeout(r, 2000));
  const jobRes = await fetch(`https://pbx-ABCD.pbxz.io/api/v1/jobs/${jobId}`, {
    headers: { 'X-API-Key': 'ULA9WHXMFCHF' }
  });
  const job = await jobRes.json();
  state = job.result.content.state;
