+# Protocol fixtures used by PrintingContractTest
+
+Unaltered copies of files from the `fixtures/` directory of the canonical `qqq-print-protocol` repository
+at commit `42c0d249f81395f00408ec0f92638dcbbf5deb03` (the commit this source pins), so the contract tests run
+without a sibling checkout. Only the files the test reads are copied:
+
+- `action-refresh-inventory.request.json`
+- `action-revoke.request.json`
+- `approval.request.json`
+- `control-inventory-refreshed.receipt.json`
+- `control-poll.request.json`
+- `create-enrollment.request.json`
+- `device-retry.request.json`
+- `device-test.request.json`
+- `enroll.request.json`
+- `heartbeat.request.json`
+- `printers.request.json`
+- `received.event.json`
+- `spooled.event.json`
+- `submit.request.json`
+- `submitting.event.json`
+- `test-label.zpl`
+
+To check these against another protocol revision, run the tests with
+`-Dprinting.protocol.fixtures=<path to that checkout's fixtures>`. When the pinned commit changes, replace these
+files from that commit's `fixtures/` directory.
