Submit a batch of print jobs

POST
/api/v1/print/{printer_key}/batch
curl --request POST \
  --url https://example.com/api/v1/print/example/batch \
  --header 'Content-Type: application/json' \
  --header 'X-Label-Hub-Key: <X-Label-Hub-Key>' \
  --data '{ "half_cut_override": true, "items": [ { "content_type": "qr_only", "data": { "items": [], "primary_id": "example", "qr_payload": "example", "secondary": [], "title": "example" }, "lookup": { "app": "example", "identifier": "example" }, "options": { "auto_cut": true, "copies": 1, "half_cut": false, "high_resolution": false, "last_page": true } } ], "printer_slug": "example" }'

Validates all items and enqueues the batch as one tape run — no per-item errors are returned. The labels (copies included) print in sub-jobs of at most 50; each further sub-job waits for POST /api/v1/batches/{batch_id}/continue. Inside a sub-job the labels go out in groups of 10 with a status check after each; when a group fails, the run stops (see GET /api/v1/batches/{batch_id}). A tape end stops it when the printer reports it: a PT sets the SNMP noPaper bit; whether a QL-820NWB reports the end of a DK roll is not verified, so on a QL the check reliably catches only an unreachable printer and an open cover. Any validation failure or hardware precondition (printer_offline, cover_open, unsupported_tape, no_tape_loaded, content_type_data_mismatch) rejects the whole batch with the appropriate 4xx status code. A page printer (IPP) answers 409 media_kind_mismatch. A printer holds at most LABELYARD_MAX_QUEUED_RUNS_PER_PRINTER (default 5) runs and a key at most LABELYARD_MAX_QUEUED_RUNS_PER_KEY (default 20); a run counts until it is over. A run that waits for /continue or a reprint counts against its key only. Over a cap the batch answers 429 too-many-queued-runs.

BatchRequest

Top-level POST /api/v1/print/{slug_or_uuid}/batch body.

object
half_cut_override
Half Cut Override

Override half_cut for all items in this batch. If the printer backend does not support half_cut (e.g. QL-Series), the value is forced to False and a warning is logged.

Any of:
boolean
items
required
Items
Array<object>
>= 1 items <= 500 items
PrintRequest

POST /api/v1/print body.

Either data (RawLabelData) or lookup (PrintLookupRequest) is provided. Exactly one of the two must be present.

object
content_type
required
ContentType

Tape-independent semantic content types for label rendering.

string
Allowed values: qr_only qr_one_line qr_two_lines qr_three_lines text_one_line text_two_lines qr_with_listing
data
Any of:
RawLabelData

Raw label payload accepted when the client supplies data directly.

Mirrors LabelData minus source_app (set server-side to ‘manual’). All content fields are optional — ContentType-specific validation happens in LayoutEngine._validate_data.

Every free text is bounded at the request (the same caps as sheet items): 512 characters per text and QR payload, at most 10 secondary lines and 100 items. A label shows far less; the renderer shortens what does not fit (#258 security review).
